I return to King David's prayer of repentance time and again: "Create in me a clean heart, O God, and renew a right spirit within me" (Psalm 51:!0). He captures the human desire so well as we long for a purity and holiness beyond our ability to attain. So I want to consider what a clean heart might look like.
- A clean heart will be joyful: "Restore unto me the joy of your salvation" (Psalm 51:12)
- A clean heart has rid itself of things that make it unclean: "Let all bitterness and wrath and anger and clamor and slander be put away from you, along with all malice." (Ephesians 4:31)
- A clean heart holds fast to and desires the Spirit of God: "Take not your Holy Spirit from me" (Psalm 51:11)
- A clean heart desires to be presentable to God: "Let the words of my mouth and the meditations of my heart be acceptable in your sight, O Lord, my strength and my redeemer." (Psalm 19:14)
- A clean heart is a treasury, carefully filled with treasures: "Therefore every scribe who has been instructed in the kingdom of heaven is like a master of a house, who brings out of his treasure what is new and what is old." (Matthew 13:52)
So the faithful are careful about repentance, about reading Scripture, studying together, and pursuing wisdom. These are some of the ways we build the treasures in our hearts.
