Create in me a pure and clean heart

"A clean heart create for me, God;
renew within me a steadfast spirit."  (Psalm 51: 12 NABR)

Unless the Lord builds the house, we labor in vain if we build it. (Psalm 127:1)  Unless the Lord creates for us and in us a pure and clean heart, we labor in vain to create it.

A steadfast and persevering spirit is also a great gift of God.  Without it, we cannot be saved.  In the kingdom, if you start a house, you must finish it.  If you start a race, you must complete it.
