5:6 Your glorying is not good. Do you not know that a little leaven leavens the whole lump? 7 Therefore purge out the old leaven, that you may be a new lump, since you truly are unleavened. For indeed Christ, our Passover, was sacrificed for us. 8 Therefore let us keep the feast, not with old leaven, nor with the leaven of malice and wickedness, but with the unleavened bread of sincerity and truth.
Few if any of us appreciate/understand/believe how complete and powerful the Good News is. We have an idea that God loves us and we think/hope/believe He has forgiven our past sins but we struggle with the present. We look at what we are and what we are not and question our position. We play all kinds of mind games to compensate for what we think we should be but know we are not. All of this uncertainty, doubt and confusion is evidence that we don't understand.
When a person chooses Jesus there is no middle ground, no ladder to climb, no goal to be achieved. The thief on the cross died the same man he was when he was put on the cross. There was no character development. There was no opportunity to right wrongs. All that happened was he made a choice. He chose to place himself in Jesus. He will rise from the grave at the return of Jesus the exact same man he was when he died. In his robe of perfect righteousness there will be not one thread of human devising. He will be declared righteous in spite of his woeful condition because of everything Jesus did.
Did you catch what Paul said in the midst of his admonition against the church people in Corinth? He declared "you are unleavened." Actually he said "you truly are unleavened." Unleavened means without sin. Paul, in the middle of correcting them for their very poor and wrong decision to allow gross sexual immorality to pass unchecked stops and reminds them of who they are. They are the sinless ones.
Why does he do that?! How can it be true? Is Paul delusional? Is he teaching cheap grace? First let me say with all the passion I can muster that grace is not cheap. Follow the life of Jesus from first to last and you will quickly recover from any false notion that grace is cheap.
Paul is telling the truth. Any person who puts their trust in Jesus and chooses Him as their Lord and Saviour is sinless. They are declared righteous. "Abraham believed and it was counted as righteousness" even though in his day to day living he was far from spotless. The confusion that exists in humanity and especially in religion is because of the false idea that our standing before God is rooted in our goodness, in our performance.
What Paul is doing is trying to remind them of who they truly are. It is the knowledge of our grace given standing before God that feeds our recovery in the here and now. We are not lost pawns in the hands of Satan doomed to his slavery. We are rescued children of a Father who loves us relentlessly. We are princes and princesses. We are of inestimable value for we were bought with a price that can't be measured. Our problem is not that we sin. Our problem is that we don't know who we are and how Good the Good News is.
The clash of the two realities really messes with our brains. We know the present reality of all that that we are and are not but struggle to look higher. The moment you chose Jesus He declared: "I tell you the truth today, you will be with Me in paradise." Your standing before God was instant. Growing into that reality is a process but that has nothing to do with the truth that we are His from the first moment we choose Him.
Unleavened. Messed up and tripping all over ourselves but unleavened. The only way to be lost is to turn from Him and follow Him no more. That’s the truth and I didn't write the Book.
