but if we don't have high moral standards in our leaders, then we as Christians become worse than the unsaved.
My point is not to call evil good or good evil, wrong right or right wrong. The Bible says in the book of Isaiah, “Woe is unto them that call evil good, and good evil; that put darkness for light, and light for darkness...” (Isaiah 5:20 ASV) But I don’t think recognizing that the policies of our rulers being sin means we should not regard them as our legitimate rulers, those whom we ought to honor, respect, and be in subjection in the Lord in so far as is possible without sin.
Sin in our rulers does not excuse our sin of speaking lightly of them, maligning their persons, or speaking evil of them. We can recognize that they are in sin, give them biblical counsel, and when asked about their policies whether we believe they are morally acceptable or not to speak the truth, but this does not justify the great sin of speaking evil against our rulers. (Exodus 22:28, Acts 23:2-5)
The honoring of our leaders and those in authority is itself a moral issue. Remember Daniel spoke truth to King Nebuchadnezzar while still respecting him, speaking respectfully and honorably of him.
“Wherefore, O king, let my counsel be acceptable unto thee, and break off thy sins by righteousness, and thine iniquities by showing mercy to the poor; if there may be a lengthening of thy tranquility.” (Daniel 4:27 ASV)
