If I said "involved with" the GOP or DNC then I misspoke (mistyped). I am speaking of identifying with a worldly power or Christ (it is one or another).You were doing OK until that last part. If a Christian is involved with the GOP or DNC and standing for Christ, then they are doing precisely what those OT heroes were doing. If a Christian is involved with the GOP or DNC but abandoning Christ, then they are not in line with those heroes.
I do not trust government as far as I can throw the White House, but government is nonetheless responsible for doing what is right, and there is nothing in the Bible indicating Christians shouldn't tell them what that is, and vote accordingly.
I am grateful Christians are involved with the GOP and DNC alike (imagine how they would be otherwise). But there is a difference between being in the world and being of the world.
