And they have acted. History, in their case, often shows a trail of action against the best interests of God's people. Jesus didn't ignore the self-destructive love of the rich young ruler for his possessions. He gave him a remedy. The compassion spoken of in Scripture sees nothing in sin that it rejoices in, nothing that it can approve.
Biblical compassion disapproves all moral departures.
Again, true compassion does not read such words or hear such messages in forensic stoicism. Some can so word a statement, that when understood in its most literal sense it doesn't lead where it does as it is actually intended. But all this is casuistry and emptiness. The Holy Spirit is never fooled. Many things are published today that begin in supposed innocence, but lead to destruction.
