“Prayer for peace in my heart” is partially based on Ephesians 2:13-18 which speaks about how Jesus is our only true peace. He makes peace between you and God by ending all conflict and hostility. But beyond just an end to disagreement, true peace is a unified heart. Pray for peace in your heart and God will give it to you.
A prayer for a pure heat. This prayer is based on Psalm 51. Purity of the heart comes from recognizing how much we need Jesus to forgive and heal us of the wound of sin. Only his loving restoration makes us new again. When we ask for forgiveness – and when we forgive – our hearts are made pure.
