one thing about celebrities -- there's no good reason i know of for us to look to them as teachers, to expect them to be sources of sound doctrine and wisdom. that's not what they become celebrities for. i haven't heard Kanye's new album but if i do i don't expect it to be like listening to a great sermon full of spiritual knowledge and illuminating wisdom. i don't expect that from Chris Tomlin or ((insert mega-popular contemporary Christian artist here)) either. when i do find that in songs it brings me a lot of joy, and when i don't i'm not anymore surprised than i am when i talk to average-church-going-joe and discover he's got a bunch of messed up doctrine he's accumulated, too.
if you can find someone who is an excellent musician / artist / whatever and a believer and has wisdom & sound doctrine, you've found something extraordinary IMO -- few and far between. Kanye, as well as all the music we hear on 'Christian radio' - and even preaching, too - we should always be listening to such things with discernment and checking them against scripture and the true Spirit of God to see if what they say is right, and we ought not be surprised to find flaws in their messages, and we ought not call them devils just because we do. which one of us is always right and has nothing to learn? famous people & people in positions of power and influence are just as fallibly human as we are.
we should pray for them, and we should pray to God to help ourselves, too.
