You might be looking at the wrong measure of what a Christian is, too. Some churches and preachers will tell you that you follow enough rules, then you are a Christian. The Bible pegs it to a personal relationship of putting trust in Jesus the Messiah, however. God has promised that if you put your trust in Jesus for salvation from sin (which is something everybody from the least to the greatest needs) then Jesus will follow through. You don't have to earn something first in order to get it. You are responsible for what you do with it when you do get it.
