Psalms 37:31
The law of his God is in his heart; none of his steps shall slide.
Psalms 37:31 (KJV)
Context
Psalm 37 is a wisdom psalm written by David. It teaches the righteous how to respond when evil seems to prosper, and it assures them of God’s faithfulness. This verse sits within that larger contrast between the righteous and the wicked.
Meaning
“The law of his God” means the whole of God’s revealed will: His commands, precepts, and moral teachings. The phrase “is in his heart” shows that this law is not merely known or recited. It is deeply internalised, shaping the person’s thoughts, desires, and choices from within.
“None of his steps shall slide” pictures a secure walk. Steps represent the decisions and actions of daily life. To slide is to stumble, falter, or be led astray. When God’s law lives in the heart, it steadies the whole path, guarding the believer from the world’s traps.
Biblical connections
This internalising of God’s law appears again in Jeremiah 31:33, where God promises to put His law in the inward parts and write it on hearts. That promise points to a new covenant work of God. Psalm 119:11 also speaks of hiding God’s word in the heart to avoid sin. Together these passages show that a heart shaped by Scripture leads to a stable life.
Application
Reading and memorising Scripture is good, but the goal is deeper. Meditating on God’s Word until it shapes our character and guides our decisions is what keeps us from stumbling. When the law of God is at home in our hearts, we gain wisdom for daily choices and protection from temptation.
Trusting God’s Word brings confidence. As we align our lives with His truth, He upholds us. This promise is not that we will never sin, but that the person who delights in God’s law will enjoy stability and security in His ways, even in hard times.
Reflection
Christ perfectly fulfilled the law in His heart, and His steps never slid. He is the ultimate example of a life governed by the Father’s will. Through Him, believers receive the Spirit who writes God’s law on their hearts, enabling them to walk steadily and to honour God in every step.
