To Baptize or Not To Baptize

I think it is very cool to watch all of the people get baptized but I wonder, what are the reasons people really get baptized? I sometimes think perhaps I should get baptized, because I have never been baptized in my life, not even as an infant. But I think the only reason I would really do it is just in case it is what I am supposed to do. Is that wrong? I won't pretend that I know the Bible at all, but from what I can tell this is not a requirement to get into heaven. So really the only reason to get baptized in front of people is so that people can see you get baptized. Or I suppose accountability. That is not necessarily a bad thing. Don't think that I am criticizing anyone that gets baptized, because I really think it takes a lot of courage to get up in front of the whole congregation and tell everyone why they are there. But if it were me, I would only be saying the words that are the right words to say. I do not necessarily believe all of the things that one who is being baptized claims to believe. Infant baptism seems to me to be something that is more of a tradition or ritual. It is really for the parents and for the families. I remember being made to feel as if we were bad parents because we did not have our daughter baptized as an infant. However, when she chose on her own free will at age 11 to become baptized, I remembered that this is why we chose to allow her to make her own choices. Every time we have baptisms at church I contemplate it. But in the end I don't do it because I don't want to be a fake. I believe in God. I definitely have faith - more than many people, I think. But I guess at the end of the day what I believe to be true is between God and me. And at least at this point in my life I do not feel as if I need to publicly declare my faith in order to be in God's good favor.
