I never trust ANY politician at their word, as words are cheap. Ditto for photo-ops. I care about what someone has DONE and what they DO. What they claim they will do should be measured by the past.
Why? Actions speak for the heart. The rest is noise/fluff.
In that regard, I cannot put my trust in Trump to abide by "whatever you did for one of the least of these brothers and sisters of mine, you did for me." Trump's history and current rhetoric give me no confidence that he has Christ-like values towards "the least of these."
Forgive me for basing my assessment on "by their fruits ye shall know them."
But, then again, as an unbelieving heathen, what do I know? I'd say just about as much as Thomas Jefferson who separated the wheat from the chaff when he composed his work: The Jefferson Bible.
Trump's pursuit and elevation of greed and lust betray whatever else he might allege to profess. That there aren't more Christians skeptical of a 70-years old man who has converted on guns and abortions (to name just two issues) just in time for a presidential election says more about their gullibility than whatever rewrite the candidate is trying to engage in.
