Another piece of an earnest prayer

Psalm 51:10 “Create in me a pure heart, O God, and renew a steadfast spirit within me.” Our lives are filled with continual prayers to our Heavenly Father while our God is always listening and responding.  I have never read anywhere in Scripture where God says or even slightly implies–this is too much, you want what?  His love is so great for each of us that we can even ask Him this morning–make my heart pure and, yes and, never let me fail You.  Those are 2 huge requests—are we sure we want to pray those? And then live accordingly? Have a great weekend.
