Where do you have the word of God, in your heart, or on your heart? That's where this thought is focused. There is a vast difference in the two positions or places. It is paramount that the word of God is in our hearts because, if it's not, it will have no effect or impact on our lives and conduct. When we look at what David said in Psalm 119:11, "Thy word have I hid in mine heart, that I might not sin against thee." Not only that hiding God's word in our heart prevents us from sinning against God, but it also gives us strength in battles, hope in despair, faith in times of doubt. It helps us to be patient, tolerant, and keeps our hearts sanctified.
