David had a prayer that is an excellent one for us to adopt to help ward off inner defilement. Psalm 19:14 says, “Let the words of my mouth and the meditation of my heart be acceptable in Your sight, O Lord, my strength and my Redeemer.”

Heart meditation based on the truths of God’s word will protect us from many diseases. God told the children of Israel that He would put none of the diseases on them that He brought upon the Egyptians. There was a condition however. 

Exodus 15:26 says, “…If you diligently heed the voice of the Lord your God and do what is right in His sight, give ear to His commandments and keep all His statutes…” Psalm 119:1-2 says, “Blessed are the undefiled in the way, who walk in the law of the Lord! Blessed are those who keep His testimonies, who seek Him with the whole heart!” A defiled heart is fragmented.
