Creator, Create a clean heart!

So, all throughout Leviticus and Numbers I've been reading about all of these sacrifices God required for different sins. How overwhelming! I do not believe I would've been able to remember if I needed to bring a male goat or lamb for my peace or guilt offering? Then, in Psalm 51: 16 David says " You do not desire a sacrifice, or I would offer one. You do not want a burnt offering." Huh? David, was obviously, living before Jesus came and was our ultimate sacrifice - so, how cool that God revealed to David this truth way before its time! Instead he realized verse 17 " The sacrifice you desire is a broken spirit. You will not reject a broken and repentant heart, O God." For me, this is a picture of my pride breaking... like a mirror smashing it! No more pride... My pride won't let me have a broken spirit, so away with it! Out! Brokenness is what He desires, not all my sacrifices of time or money if they aren't in a right heart. Verses 10-12 "Create in me a clean heart, O God. Renew a loyal Spirit within me. Do not banish me from your presence and don't take your Holy Spirit from me. Restore to me the joy of your salvation, and make me willing to obey you."  God is the Creator of all... and I often forget, He still creates, everyday - every minute. Create a clean heart in me, Creator!! Make me willing to obey you... I think I forget I can pray that God will help me obey Him if I pray and desire that!
