Create in me a clean heart
"Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions. Wash me thoroughly from mine iniquity, and cleanse me from my sin... Create in me a clean heart, O God; and renew a right spirit within me." ( Psalm 51:1-10 ).
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. ( 1 John 1:9 )
"Christ is the source of every right impulse. He is the only one that can implant in the heart enmity against sin. Every desire for truth and purity, every conviction of our own sinfulness, is an evidence that His Spirit is moving upon our hearts." (Steps to Christ, 26)
When I'm entirely ready to have Father God remove my character defects, it's a natural next-step to ask Him to do it. However, the way He does that is sometimes unexpected and often painful. My tendency is to want God to sprinkle some "pixy dust" on me and POOF, I'm all better! But it hasn't happened to me yet :-) What has happened is according to Hebrews 12:5-11 . God has given (and still gives) me consequences for my bad choices. Forgiveness (in my case) seldom removes all the consequences. And I have some doubt that my character would actually be changed much if all consequences were removed. In my estimation, some of the ingredients of character transformation are: consequences, accountability, right choices (strong hard battles with self), and complete reliance upon God for my strength.
