Ok, I am not married, however, I do have some fresh insights on the enormous changes that occur between the ages of about 16-20. There are some serious maturity changes throughout those years so right off the bat my advice would be to wait at least a few years. But here are a few other things to consider.
You are 17, you are not even out of high school yet, most likely. Have you ever held a steady job? Have you ever dealt with your own finances? Have you ever bought all your own meals or cooked for yourself and paid all the bills? Do you make, or can you make enough to support you and your wife and a kid or two? What do your parents think of the whole thing? What does your pastor think of the whole thing? What does godly counsel think for the most part?
You don't need to answer these questions on here, I just am throughing them out there. I don't even know if you have someone in mind or not.
However, as a side note, and please don't take offense at this, you have a UN flag as your flag. That basically tells me that you don't have a clue about the world (unless you are from UN controlled, there is an oxymoron, part of the world). I say that in love. Before you start thinking about getting married, you need to start thinking about prepairing for marriage.
I will say this to. When I was 17 or right when I turned 18 I began to think about getting married, and I realized that I had a lot to get done before I should even consider getting married.
