I agree. Osteen is not perfect, his messages are mostly fluff but he is entertaining and he brings people to Christ. People condemn him and most tv preachers. But they are spreading the word, and that is a good thing. I guarentee Osteen and others have brought many more people to Christ than I have or any of his critics for that matter.
Certainly I cannot know for sure, but it does bother me that his messages don't seem to emphasize repentance. It causes me concern that someone may "come to Christ" for what they might get from Him material-wise, without the repentance and surrendering of themselves that Jesus expresses is vital to believing on Him. What if, by not getting the full message, they are missing out on who Christ is and what He is about and therefore not really being saved at all? False doctrine (like Osteen's claim that the death on the cross was not sufficient by itself) can mislead people - the Bible says so.
Oh I can assure you, the Lord uses Osteen to bring more people to Himself in a short season that all these critics in a lifetime. What can you do?
