So, does it really work?

Genesis 24
10 Then the servant took ten of his master's camels and left, taking with him all kinds of good things from his master. He set out for Aram Naharaim and made his way to the town of Nahor. 11 He had the camels kneel down near the well outside the town; it was toward evening, the time the women go out to draw water.

12 Then he prayed, "O LORD, God of my master Abraham, give me success today, and show kindness to my master Abraham. 13 See, I am standing beside this spring, and the daughters of the townspeople are coming out to draw water. 14 May it be that when I say to a girl, 'Please let down your jar that I may have a drink,' and she says, 'Drink, and I'll water your camels too'-let her be the one you have chosen for your servant Isaac. By this I will know that you have shown kindness to my master."

I've mentioned that I've been working on my own independent study of prayer. This is a prayer of one of Abraham's servants. And God answered it by sending Rebekah, and she did as he prayed and she was the one for Isaac. More than once I've wished God would just send the sign, the burning bush, the cloud of smoke leading the way. And I have prayed a prayer like this when I was scared to death that God was calling me to make a mission trip. And he answered each prayer in a way that was without question an affirmative: Yes. Go. God is full of mercy and he knew that nothing less would get me moving. But I've also wondered whether this reflects a lack of faith. Is this a way to test God or is this a way to search God's will and know?

I've been thinking about this for the past week because I feel like I'm facing a big decision. I know how I feel in my heart, but my head tries to be logical, to make the proper decision regardless of how I "feel" right now...the best decision for my future. And, as logic really isn't my strong point, especially in personal decision making, it's a struggle. So today I was driving on the way to my next hurdle, the normal feeling of dread riding shotgun, and I was just basically talking to God...and I said, "You know, if I don't see results tonight or if this person calls me to tell me she can't make it again, I'm going to know the right decision to make" never really believing that it would ever be that simple. I arrive. I'm bustling to be prepared. And she calls to say she won't be able to make it. So...now what? Is that answered prayer? After the first epic battle over the Peru trip, I've never believed in coincidence. If I put on my ill-fitting logic hat again, here's what I know:
1. God answers prayer every day. Maybe not always in ways that I hear, but I believe they're answered.
2. God answers through His word and His people. Both seem to be at work here.
3. I've been asking, seeking, knocking for some time. God promised to answer.
4. When I think of making this decision, I feel peace. I worry over tomorrow, but today I will feel happy, unburdened, at peace. Since God has promised to take care of tomorrow, maybe today is what matters.

I think I have an answer.
Quick, somebody with better logic...point out the flaws in my reasoning!
