These circles get so tiring. Everyone over-exhaggerates what the other is saying to make them out to be a moron, this way there is no reason or logic not to be believe as they do. NO ONE is discounting repentence and the role it plays in salvation. The issue is whether or not it is a repeated act. The issue is whther the act of salvation was finished upon its acceptance or a constant ritual of sacrifice for sins to be blameless by the law.
"And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me."
"Buried with him in baptism, wherein also ye are risen with him through the faith of the operation of God, who hath raised him from the dead.And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him,
having forgiven you all trespasses; Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross; And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it. Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: Which are a shadow of things to come; but the body is of Christ...Wherefore if ye be dead with Christ from the rudiments of the world, why, as though living in the world, are ye subject to ordinances, (Touch not; taste not; handle not; Which all are to perish with the using

after the commandments and doctrines of men? Which things have indeed a shew of wisdom in will worship, and humility, and neglecting of the body; not in any honour to the satisfying of the flesh."
If we say we are freed from the bodage of the law by the sacrifice of Christ, then by what standard am I judged? If not by the law of God, of His widowm and judgment, spoken by His Word, then by what? Who can call me a transgressor, seeing I have no law to be judged by (save one in Christ by whose example I am saved)?
"Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand."
