Psalm 119.11 I have stored up your word in my heart, that I might not sin against you.
This is also a word that has followed me from my youth. I have experienced what the psalmist is talking about. Therefore, I have written this truth in one of the first pages of my Bible: This book will keep you away from sin, or sin will keep you away from this book. There is a deep truth to this.
When we store God's Word deeply in our hearts, we will be led and motivated by the Word to do what is right and good and to avoid that which is sin. With the Word of God in our hearts, we will be aware of what God wants to do for us and through us. When the word of God dwells in our hearts, we will know God's will and be able to choose the right path when we have to make choices.
