Moses was a murderer; David was an adulterer; Samson was a fornicator.
But God saw fit to use such unworthy vessels for His holy purposes: to lead His people Israel.
By contrast, this here is just a temporal, secular office, the United States presidency. It is not a holy calling.
And so if God can choose men who have lived ungodly, unworthy lives for holy purposes, how much more can a mixed group of Christians and unbelievers together decide, if they please, to choose a man who has lived an ungodly, unworthy life for a secular, temporal endeavour, the United States presidency?
Stop throwing pissy, sissy, hissy fits.
