It is in the moments where right after sinning, you feel the weight of your sin. You realize exactly how helpless you are without Christ in anything. If I cannot even be consistent in simply controlling my temper, how in the world am I to walk in an unhindered fellowship with our holy Father everyday? How can you ever have intimacy with a God detests sin? "I thank God through our Lord Jesus Christ!"
The truth that I'm no longer suppose to be conscious of the sin that dwells in me is amazing!! I don't have to go through that condemnation, re-dedication cycle where I pout to God about how much of a dead dog I am, and how I am not worthy of anything. Then I eventually muster up the motivation to try again. Whereas in grace, I can simply say "Thank you, Father for Jesus!!!!!" and get right back up, asking for His Spirit to change me. Realizing that Abba isn't ashamed of me or angry with me, removes those times of "time out" I usually give myself before I'm able to come again boldly to the throne of grace. How do you come boldly? By grace!!! Just accept the grace. I know it hurts, but you'll get over it.
Normally, I would beat myself up, call myself a poor excuse for a Christian, and wonder how in the world I could ever get people to know Christ when I continually fail at representing Him.
But now, I think representing Him is not so much being perfect, but being full of grace and truth. The truth is realizing we are as dead dogs. Grace saying that doesn't matter. God loves you no matter how much you stink or how filthy you may be. Because His Son has reconciled the world to Himself.
Maybe representing Christ is showing His agape and grace to others by being real to them about your flaws, but showing them how much God still accepts you and loves you. I'm not very smart, but I think sinners are more attracted to grace, rather than perfection. A sinner cannot bear to be around a human who is perfect or self-righteous. That just makes them feel like utter sin and gives them all the more reason to continue in sin, because from their perspective, they will never be able to qualify for God's love. I would know. I've been there.
