Not only is OP way too young to be worrying about it, at 19, when he's looking toward marrying when he's 25, but we need to trust in God.  

I disagree.  If the OP is planning on marrying in 6 years, wouldn't NOW be the time to be planning and preparing?  I think it shows a good foresight on the part of a young man to want to start caring for his future family.

That being said, it's always a good idea to have as little debt as possible.  Agree with all the above on practicing a trade, with your hands, rather than a desk job.  

Have a house bought, and pretty substantially paid for, before marrying; if possible.

By the way, to the OP, don't get discouraged if by 25 you haven't married yet.   If there's any kind of a major age difference between you and your future spouse, it may be that you're older than 25.  Just look at it as more time to prepare for a family and more time to practice self-denial and sacrifices, both very neccesary in a father/husband.  

Seek ye first the kingdom of God, and all these things shall be added unto you

When my husband and I got married we were living in a rundown studio apartment. When we fully committed to God's will (we are converts) and I got pregnant, we were renting half a garage and I was budgeting $60/week for our groceries and necessities. It's been about two years since then, but we're now living in our own home on a substantial amount of land with our second son due in a couple weeks.

Things will fall into place however God intends them to, just make sure first and foremost that you never stop seeking His will and justice (this is roughly the same advice Bp. Williamson gave to my husband a few years ago, which helped us tremendously).
