There is a difference between begging and praying. Praying is simply asking God for something. Now I think you can "pray hard," that's great, and I think you pray regularly for something, but there's a line you cross when you start thinking "God please give this to me or I won't be happy." That's when you know you probably a) won't get it, or b) you won't want it when you do.
And there is a difference between trust and laziness. Trusting that God will take care of you is vital in our walk with Him. I could be extremely stressed about my possible summer internship right now, but being stressed about it won't help me get the internship. Instead, I need to trust that God will work it out for His glory and my good.
But then again, you can't just say "Oh God will take care of me" and not do anything about it. Saying "God will give me an internship" and then sitting back and waiting won't help me.
And another thing: There's a difference between jumping in to trust God, and making dumb choices. For example: When I chose Criminal Justice as my major. I could have agonized over "oh what am I going to major in!" but I didn't, I just picked something and went for it and figured if it wasn't part of God's plan, He'd throw up a roadblock and point me in another direction. And when I switched majors it was the same thing.
Now with John, I was a bit more careful about "jumping in." but that mindset was definitely there after it was clear that he wasn't just going to pursue me, seduce me, and leave me. He and I were both in it for the right reasons, we had the same goals, we have the same beliefs about marriage and relationships, and we are both in it for the long haul. we're DEFINITELY compatible (if you can call it that…). so then I had to chose to jump in, after all that important stuff was clear.
and I could have said no. Because remember, he had an ex-girlfriend who had him thrown in jail, and his gpa isn't so great, and he's not very book-smart, and I know a grand total of two people besides me who think he's attractive. But I was pretty sure I loved him, and he was exactly what I asked for, so I jumped in.
"Why do you always bring your boyfriend into it, em? knock it off!"
The point is, you can ask through prayer, you can trust God, and you can jump in. But when it all comes down to it, no matter what you do and what choice you make, eventually you'll find the open doors (after you run into enough closed ones). but you've got to be willing to ram your face into some doors first.
and really, it doesn't hurt quite as much as you think.
And it's always worth it.
