Psalm 51

Create in me a pure heart, O God, and renew a steadfast spirit within me..

Restore to me the joy of your salvation and grant me a willing spirit to sustain me.

Then I will teach transgressors your ways, and sinners will turn back to you

Psalm 51:10-13

A transformed heart is like a magnet set near a compass - it disturbs and realigns the direction of those it comes close to.
