MM agreed with blue and oblivious... ChildOfGod... Yes it is important that we make sure it is in God's timing, but as i have been taught at church (and makes logical sence to me), his timing isn't always that much about hearing from him, or "knowing" as they so often fail us. It is more about making sure circumstances are all in the right place (ie ready for marriage), feeling peaceful, not going against god's will (ie non christian, rules are pretty much in the bible), and particually counsel of others... and for the counsel bit, that isn't your friends who so much want it to happen, mainly older christians...
You see, being ready for marriage is a BIG deal before you get engaged... I was engaged at 17-18 and we were waiting about 3 years... As you can tell by the word "was" i no longer am. Now everyone who knew (rather private it was) was so happy, and sure we would, and were equally suprised when we broke up just under a year later. It's not all about the "knowing", because esp us younguns, think we "know" it all... And quite frankly we dont'.
yeah ok, so i'm now engaged... The difference is, those things line up with each other... We are able to get married anyday (if it wasn't for a 3ish month mission trip i'm going on) and we only are waiting 1 year because we want to have time on ourside, and make our parents more comfortable with it.
