Unfortunately, they probably will feel they should help God along.
I know the feeling. "Vengeance is mine, sayeth the Lord" is probably the one thing is the Bible that I have the most trouble with. I constantly struggle, not against taking vengeance, which I don't, but in feeling comfortable with not doing so.
Somehow, I don't think that they will be so troubled.
Trust in God has been a problem since the first man...
helped along, of course, by His enemy.
