Well that's kind of a moot point because a core concept/teaching of Christianity is that "all have sinned and fallen short of the glory of God" and thus Jesus is the way/the truth/the life - no one gets to be with God except through Christ. So the goal is to certainly be as Christ-like as possible, but one can never truly be Jesus incarnate on a moral or virtuous level. Everyone screws up at some point, but Christ's death keeps our sinful slates forgiven.

But I mean that's just the message from Christianity and there are other religions and beliefs out there. Ultimately you have the freedom to choose what you want to believe and in this lifetime we have no way to truly know what the right belief system is or even if there is something for us after our physical bodies fall apart and stop functioning.

So if you want to believe in heaven and make sure you can get there when you die, there's more than just Christianity that carries that concept. It really just depends on what you want to or can come to believe is true, and believe strongly enough to put all bets on it. For me, all bets are on Christ.
