Jesus said a lot of things, some were meant to be taken literally and lived out to the letter. Other things he said were parables, stories meant to teach something, but not to be taken literally. Then there are statements made that are more "in the middle" and a combination of the two. We are to "go and make disciples", but many of us can't reach people by 'preaching' or 'witnessing' to them. That never worked on my dad. What worked on my dad was watching others live their lives and beliefs each day. Tyler is doing what he feels convicted to do. Additionally, Tyler may be like me, I'd never put a "Christian" bumper sticker on my truck - I'd forget it was there, but others would NEVER forget it and I may act in a way that destroys a person's perception of Christianity - so now bumper sticker for me. Am I not 'making disciples'? Anyway, Tyler is in the public eye - maybe he is afraid that openly being Christian would hurt his record sales, or, maybe he just does not feel qualified and called to preach and teach. I'll leave that between him and God.
