Don't listen to those people on this thread trying to tell you are too young to marry. It is so ridiculous that 24 is considered too young by many in our society. Go for it. Just make sure before you get married that you and she are on the same page about your values and family plans.
Good luck and God bless.
People at the age of 24 simply do not have the life experiences that older folks do. That's not to say that this person needs to be a playboy and shack up everywhere he can. But, to be married successfully you have to have a sense of yourself in terms of who you are and who and what you are not. You generally don't figure that out till later on down the road.
