I make different choices.
I choose to remain skeptical of NTM until proven otherwise, because of their track record. Actually, I have no personal stake in the outcome either way other than as a fellow human. In that, I side with those who have been waiting so long for justice and vindication. When they are satisfied, I and the rest of compassionate watching humanity will be satisfied.
I (choose?) logically believe that my husband's parents and anyone else who left their children behind to share the gospel fully missed the point of the gospel- Jesus' great command to love one another as he loved us, and to care for the least of these as if they were Jesus himself. Obviously anyone abandoning Jesus so they can go tell other people about him have missed the point. I don't believe they were evil, but very misguided. I do think they wasted their lives, though God brings good out of evil all the time, it is no endorsement of evil. Abandoning children for any reason other than the welfare of those same children is evil in my opinion.
I am not sure what that means about doctrinal fights. It looks to me like all the people who disagreed with fundamentalism have left or gone silent, so there's nothing to discuss there.
I care very deeply for my MK and every other MK who wants my sympathy and support.
Yes, all have sinned and fallen short of the glory of God,which is why the Savior came to reconcile not only us, but the whole world to God. That is the good news I share, that God was in Christ, reconciling the world to himself and no longer holding men's trespasses against them.
There is no free pass in the Bible for child abandonment (or any other willful sin) for Christian workers. I profoundly disagree that God called anyone to every do that, not even once.
