Sermon Idea: Those who delight in God store His Word in their hearts and speak it with their mouths.
Introduction: Are you familiar with the name John Bunyan? He was a 17th-century English Puritan who spent over a decade in prison for preaching the gospel without government approval. His most famous work is an allegory of the Christian life called The Pilgrim’s Progress, which is delightful to read and offers much reflection on how to persevere in hope as we make our way to glory.
I mention John Bunyan this morning because of what others remembered and said about him. There is no greater example of this than the reflection of Charles Haddon Spurgeon, who, while preaching two hundred years after Bunyan’s death, said that those who read him can’t help but say:
“Why, this man is a living Bible!” Prick him anywhere; his blood is Bibline, the very essence of the Bible flows from him. He cannot speak without quoting a text, for his very soul is full of the Word of God.”
That is high praise coming from Spurgeon, someone who would later earn the nickname, “the Prince of Preachers.”
I want you to take note of exactly what is being praised. It is not bare biblical knowledge itself. Spurgeon does not praise Bunyan for being an encyclopedia of biblical knowledge. Spurgeon sees in Bunyan a soul nourished and formed by Scripture. In Spurgeon’s words, Bunyan’s “very soul is full of the Word of God,” so that if you were to prick him, his very blood would be biblical. In other words, Bunyan did not merely know the Bible, but was transformed by it.
As people hear you speak and as they see you act, what conclusions would they draw about what has nourished and formed you? If someone were to prick you, if we can keep the imagery alive for a moment, what would your blood testify about your soul?
The second stanza of Psalm 119 gives us Holy Spirit-inspired, perfect guidance about how to become a person whose very life is formed by the Word of God.
As we have said, our exposition of Psalm 119 can be summarized with two words: discipline and delight. We want to be a people who give ourselves to a disciplined hearing and reading of the Word of God, so that we might delight in it and, in turn, delight more in the God of the Word.
How does Psalm 119:9-16 help us do that this morning? If we can capture its message in just a sentence, it would be this: those who delight in God store His Word in their hearts and speak it with their mouths.
I.) Those who delight in God store the Word in their hearts (Psalm 119:9-12)
The opening question in verse 9 sets the theme for the rest of the stanza: How can a young man keep his way pure? By guarding it according to your word (119:1)
This is a Word from God to all of us, but He mentions young men for a reason. Young men can make a mess of their lives if they don’t direct their passions and desires well, and the stakes are high because those early formative years also shape the kind of grown man they will be.
Brothers, the seeds you sow in your youth, you will have to reap when you’re older. So don’t waste your strength, your youth, and your time on that which will not benefit and edify you in the future.
It seems that this is meant to work as a principle from harder to easier. In other words, if the answer provided is sufficient to keep the purity of young men, then it’s sufficient for men and women of every age.
The answer is, “by guarding it according to your word.”
To guard our lives according to the Word means more than trying really hard to obey it. Rather, the Word serves as a guardian or protector for our lives, because it shapes and forms us.
Here is a beautiful truth to consider as you seek to have your life guarded by the Word of God: Jesus has prayed that the truth of God’s Word sanctify us, and he is the example of guarding his life according to the Word.
Sanctify them in the truth; your word is truth (Jn 17:17)
19 And for their sake I consecrate myself, that they also may be sanctified in truth. (Jn 17:19)
What’s my point? Jesus is for you as you pursue a life guarded by God’s Word. He is not only for you, but is praying for you as you seek to be shaped and formed by the Bible. He prays that you would be sanctified by God’s truth.
Robert Murray M’Cheyne once said, “If I could hear Christ praying for me in the next room, I would not fear a million enemies. Yet distance makes no difference. He is praying for me.”
How can we better understand what it means to guard our lives according to the Word? Verses 10-16 help us with that, starting in verse 10: we are to seek the Lord with our whole hearts.
With my whole heart I seek you; let me not wander from your commandments! (Ps 119:10)
If we are going to be a people who delight in the Lord, then we must be a people who prayerfully seek the Lord with our whole hearts. The two phrases of verse 10 go together. We seek to know, worship, and obey the Lord with our whole person from the heart.
Those who delight in God are not satisfied with the appearance of godliness. Those who delight in God will not settle for merely being applauded for external acts of service. Those who delight in God understand and believe Isaiah and the Lord Jesus, that it is possible to acknowledge God with your mouth while your heart is far from him.
7 You hypocrites! Well did Isaiah prophesy of you, when he said: 8 “‘This people honors me with their lips, but their heart is far from me; 9 in vain do they worship me, teaching as doctrines the commandments of men.’” (Mt 15:7–9)
Those who delight in God have no desire to be described as Paul describes wicked men to Timothy, as those, “having the appearance of godliness, but denying its power.” (2 Tim 3:5)
The primary way to seek the Lord with our whole heart is to pray that the Lord would not let us wander from his commandments. Reading and reflecting on Scripture is a spiritual exercise. It is not like following an instruction manual for putting furniture together. You can know the commandments while your heart is apathetic towards them.
So, as those who seek to guard their lives by the Word, we pray fervently for God to keep us, stir our hearts to love the Word, rejoice in his commandments, and obey him with a sincere heart.
You will not understand the necessity of such a prayer until you admit and acknowledge your own propensity to wander. Those who delight in God know that without his grace and the Spirit’s help, their heart will chase a whole host of things not worthy of their attention. That is why it’s helpful to sing that last stanza of Come Thou Fount.
O to grace how great a debtor
daily I’m constrained to be!
Let that grace now, like a fetter,
bind my wandering heart to thee.
Prone to wander, Lord, I feel it,
prone to leave the God I love;
here’s my heart; O take and seal it;
seal it for thy courts above
Given our proneness to wander, we should take special heed to verse 11. How can we preemptively attack our own weakness and temptation to sin? We store the Word in our hearts.
I have stored up your word in my heart, that I might not sin against you. (Ps 119:11)
I really love the way John Gill comments on the Psalmist’s meaning in verse 11: “Not only heard and read it, but received it into his affections; mixed with faith, laid it up in his mind and memory for future use; preserved it in his heart as a choice treasure, where it might dwell richly, and be of service to him on many occasions…”
I want you to imagine briefly that you are in a circumstance or situation in which you don’t have access to a Bible—not a physical copy, an app on your phone, nothing—but the circumstances are so dire you’d need the Word to persevere through them. How much of the Bible could you access in your own mind and heart? How much of it would be so stored up in your heart through memorization that you could meditate on it without ever seeing it on a written page?
One of the most underutilized spiritual disciplines among so many Christians today is memorizing Scripture. The Lord commands that we not only read the Word, but that we store it in our hearts like a precious treasure. The Bible’s encouragement to memorize Scripture is greater than you may think.
6 And these words that I command you today shall be on your heart. 7 You shall teach them diligently to your children, and shall talk of them when you sit in your house, and when you walk by the way, and when you lie down, and when you rise. (Dt 6:6–7)
If you abide in me, and my words abide in you, ask whatever you wish, and it will be done for you. (Jn 15:7)
16 Let the word of Christ dwell in you richly… (Col 3:16)
When I was in seminary, I had the opportunity to take a class on Jonathan Edwards with Dr. Andy Davis, pastor of FBC, Durham, North Carolina, who occasionally teaches church history classes on campus. From the first day of class, I was struck by his presence and the way he spoke of Scripture. It felt like, “…this guy walks with Jesus at a different level than I do.”
What I came to learn, and what he is known for now, is that he has committed entire books of the Bible to memory and has been disciplining himself to do that for over thirty-five years. The Bible has 66 books, and as of 2017, when I was in his class, he’d memorized 42 of them. Sitting in his class is my closest personal experience to Spurgeon’s reflection on Bunyan.
I want to encourage you to think about how you might better memorize and store up the Word in your heart. I also want to challenge you not to fall back on the typical excuses. Your memory is good enough; you can make time, and there are resources available to help. Chief among them is Dr. Davis’ little book, How to Memorize Scripture for Life: From One Verse to Entire Books.
Those who delight in God store the Word in their heart, so they may not sin against God. No greater antidote to sin exists than internalizing God’s Word. This is how the Lord Jesus endured Satan’s temptations in the wilderness. Three different times Jesus said, “It is written.”
Notice also verse 12, which combines praise and prayer.
Blessed are you, O LORD; teach me your statutes (Ps 119:12)
The Lord is the fountain of all that is good, true, and beautiful, and in Christ God becomes our teacher. You can pray this prayer with confidence, because if you’re a Christian, you’ve already begun to be taught by God.
45 It is written in the Prophets, ‘And they will all be taught by God.’ Everyone who has heard and learned from the Father comes to me— (Jn 6:45)
No one is a greater teacher than God the Holy Trinity: Father, Son, and Holy Spirit. If you’re in Christ, then you’ve been taught by the Father, and if you’re in Christ, you’ve been given the Holy Spirit, whom Jesus promises in John 14 will be our teacher:
the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you. (Jn 14:26)
So friends, pray for God to teach you as you hear the Word preached. Pray for God to teach you as you read the Word. Pray for God to teach you as you memorize the Word.
Those who delight in God store the Word in their hearts.
II.) Those who delight in God speak the Word with their mouths (Psalm 119:13-16)
Verse 13 shifts from internal digestion of the Word to external declaration of the Word. Those who delight in God not only store the Word in their hearts, but they speak the Word with their mouths.
With my lips I declare all the rules of your mouth. (Ps 119:13)
Rather than talk through the second half of the stanza verse by verse, I want to mention three ways those who delight in God declare all the rules of God’s Word.
- Speak the Word to evangelize and disciple
“In this verse he declares that the law of God was not only deeply graven on his heart, but that it was his earnest and strenuous endeavor to gain over man of his fellow-disciples into subjection to God.”- John Calvin
2. Speak the Word to edify
29 Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear. (Eph 4:29)
14 And we urge you, brothers, admonish the idle, encourage the fainthearted, help the weak, be patient with them all (1 Th 5:13–14)
3. Sing the Word to exalt God and encourage the people of God
16 Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God. (Col 3:16)
but be filled with the Spirit, 19 addressing one another in psalms and hymns and spiritual songs, singing and making melody to the Lord with your heart, 20 giving thanks always and for everything to God the Father in the name of our Lord Jesus Christ, 21 submitting to one another out of reverence for Christ. (Eph 5:18–21)
In these three manners of speaking the Word, we obey and adhere to verses 14-16.
As we speak the Word to others, we meditate on God’s precepts and fix our eyes on them (Psalm 119:15)
As we sing the Word to edify the church and exalt God’s name, we delight in God’s testimonies as in riches; we meditate on his precepts through song, and delight in God’s Word, so that we will never forget it (Psalm 119:14, 15, 16).
Those who delight in God speak his Word with their mouths.
In closing, it would be good to offer some points of application that may seem obvious, but are important to hear again given our culture’s rampant biblical illiteracy and the importance of knowing God’s Word.
- Keep a Bible with you, and reference it throughout your life.
- Read your Bible, all of it, as much as you’re able.
- Study Scripture in depth. Connect with good Bible studies, come on Wednesday night, join Precepts, and use good resources.
- Pray the Bible. Pray the very words of Scripture, for we know that prayers according to God’s will are answered (1 John 5:14-15)
- Sing the Bible. Sing the Psalms, sing Scripture-saturated hymns. Do so in corporate worship, but also around your kitchen table.
- Share the Bible with others. Evangelize the lost, counsel sinners and sufferers, and edify the saints.
