Living for the eternal

I do believe that Christ took the judgment from God that I rightly deserve by dying on the Cross and through that He gave me His righteousness and the gift of eternal life in Heaven, BUT if I were to die right now and go to Heaven but find that Christ was not there, would I be OK with that? Something to ponder... as Christians it's so easy for us to say "oh yeah I believe I'm going to Heaven" but do we really understand why we should want to go to Heaven?
