No it doesn't. From what I've experienced and felt in my life, I can envision what Heaven may be like and what may happen when I get there. Based on my own understanding of God that is what may be possible in Heaven. Do I know for sure that's what will happen? Fuck no. I could be completely wrong. But I'm not too worried on whether I am or no at all; it doesn't pay to use one's entire human life worrying about what the afterlife is like. Regardless of whether you're Christian, atheist, Buddhist, Hindu, Islam or what-have-you. Best let things take care of themselves when you get to that point.
