I have stored up your word in my heart, that I might not sin against you.
This is so we are continually guided by the Lord’s precepts. Our default as humans is what we think is best, and that will always be self-serving. God’s word opposes our nature, which is why memorizing it is so helpful.
The meaning here of ‘stored’ means to conceal or treasure, much like someone would do with money or jewels. This really implies that the word of God is a treasure, which is absolutely true.
Work today to remind yourself of how valuable God’s word is. We cannot possible live in a way that glorifies Him without it. Humble yourself to recognize your need for His guidance, so you might not sin against Him.
