Dear Gene,
The Old Testament was written long, long before Jesus was born. It was scriptures from it that He corrected, e.g. "It is written 'an eye for an eye, but I say unto you do good to those who do evil to you.'"
This on its own would seem to support the argument that Christians should, as Harry, you, and others here suggest, sit down and shut up when Trump does evil. There is however an example of how someone announcing the coming of Christ behaves in relation to power being abused.If you believe that Jesus is coming again, as He promised, then consider the example of John the Baptist, who scripture tells us came proclaiming the Messiah's arrival, but also speaking "of all the evil things the king had done." Indeed, this is what cost him his head, not his religious prophecy. If we do not condemn evil we become silently complicit with it. Trump IS evil.
So there.
