The quiet and unassuming power of the grace of the gospel turns the defiled heart inside out. Then the cleansing purification of salvation in Christ lifts the filth out of every crevice. And faith ultimately turns the heart around until it beats beautifully with joy.

Create in me a clean heart, O God,
    and renew a right spirit within me.
 Cast me not away from Your presence,
    and take not Your Holy Spirit from me.
 Restore to me the joy of Your salvation,
    and uphold me with a willing spirit.
Psalm 51:10-12, ESV
