Does God command Christians not to vote for Trump? I know that this is a very controversial question, but let's consider what the Bible says in I Corinthians 5:11.
"But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat." (1 Cor. 5:11)
"Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning." (Proverbs 9:9)
