Sorry, too much TV and not enough biblical reading. Your description is not to be found in Scripture. Cain was rejected, Esau was hated, Pharaoh was hardened...shall I go on? There is, according to Paul, no distinction between the man and the resultant behavior. The adulterer is denied faith, the incestual man is to be pushed out of a fellowship, not because they are unsalvageable (any more than we are), but because their behavior is evidence that they are being presently excluded. We are to allow God to grieve them and bring them back (if He wishes), but we are not to slather love and affection all over them and confuse the issue. You have watched too much Joel osteen. He is not teaching truth.
Maybe you are reading too much of one passage forgetting the OTHER passages in scripture.
Did Jesus Christ reject being friends with sinners ( even as he did not condone their sin)?
Let’s not forget, Jesus said “Those who are well have no need of a physician, but those who are sick. I have not come to call the righteous but sinners to repentance.” (Luke 5:29-32).
Aren’t we supposed to follow His example as His disciples?
The church did the right thing in firing the man because he was unrepentant. But the objective is to pray for him, and hope for his repentance, not give up on him totally.
THAT’s what I mean by the man being redeemed. It has nothing to do with Joel Osteen.
