Did Jesus succeed? He certainly did in the hearts of those that have chosen to truly follow Him, but the world in general? Yes, His message is plainly evident. But is his message of reconciliation with God one the world is keenly trying to follow? Heck, even some of those who proclaim themselves part of the Church He founded seem to sometimes use His name to justify absolute horrors. I think we have a long way to go before His message is clearly witnessed by those outside of His faith. Note I wrote "witnessed", not heard.
What do you mean he didnt succeed? there is already churches dedicated to him..he must have been succeful
