In their defense, if there were ever someone that Christians needed to pray for (so that they change their ways) it'd be Donald "I'm a very stable genius" Trump. Somehow I doubt that was foremost on their minds. Probably more "may You bless us and give us great blessings as we spread Your word and see Your will be done [which happens to be whatever the hell we say it is, even if it directly contradicts the Bible]."
The only context you need is that Christian evangelism supports the anti-christ; the physical embodiment of the seven deadly sins, and antithesis to the words of Jesus Christ.
It's worth reiterating. The context IS mental illness.
Having know some evangelicals, it doesn't hold any huge significance. They'll lay hands on someone who has a broken arm to pray to God to heal it, so it's not like this is a huge honor. Still weird, but this isn't a sign of them idolizing him, especially compared to that golden goat statue with Trump's face on $100 bills. The goat is literal blasphemy, but "laying hands" is just how evangelicals normally act...
Yeah, pretty much. I'm not saying it isn't weird, and I'm also not saying they don't idolize him, but this picture is just how evangelicals treat other evangelicals. Nothing scandalous or newsworthy, IMO.
