I happen to think that
@Saved Christian is on the right track. That God does not intend Man to be deciding for himself what is right for him, that Man should receive everything from his Creator.
So when Man choose to eat from the tree of the knowledge of good and evil, he took upon himself that responsibility to choose for himself, and a whole new vista of possibilities opened up.
Until that moment, there was only, receiving what God gave, but that choice led to a new paradigm, that there was an alternative to God's way. Man had discovered evil.
The mind of the religious person is according to that way, trying to be suffuciently "good" to be accepted, but in Christ, we are removed from that humanity, into a new humanity, with the new way, the original way, living according to Life, the life Chrsit gives us, not in some alternative.
The renewing of our minds it to get us away from that old mindset of choosing for ourselves the details of our lives, though there is a part for us in that, I hope you understand what I'm saying, but to get rid of that now obsolete paradigm, stop living our lives as if it were still true for us, and start living according to the new reality. To find that this is in fact the new reality.
Another way I like to describe this is to say living according to a complete reconciliation to God. No more concerns over good or evil, only to bring ever errant thought to Christ to be submitted to Him. And to recognize when we've stopped walking in the light of Christ's life.
Much love!
