Well... that was the basis of christianity, people all have there own opinions of christianity. To be like Christ is a literal translation of the word christian. And Jesus went around healing people, offering salvation and forgiving. If you ask me those are pretty good things. So in my opinion Christians should be like Jesus, but most tend not to be. and it is always a constant struggle to continuously sacrifice yourself for others, and just do good over all, but i still try.
On another note, religion is not necessary. You can still be a very good person and respect, honour, and love everyone you meet, without having any religious beliefs. So if you feel that you don't belong in a religion, just go around doing good deeds without one.
