Abraham

This week seems to be a continuous circle of Bible stories.  It seems that Abraham seems to be the theme for the week, for some reason, his life keeps coming up.  I am reminded of parts of the story that I had forgotten, and been told parts of the story I never realized.  I've noticed that when I read the Bible, I tend to focus on certain parts of the story, and forget the rest.  I love the story of Abraham, when God tells Sarah that she's pregnant, and she laughs.  It's such a simple line between her and God that makes me laugh, because I feel like it's a line from How I met your Mother,
God  "You laughed"
Sarah "I did not laugh"
God, "Yes, you did laugh"
I don't know why, but I love it!
But anyways, another part of the story that I tend to overlook is the part where Abraham tries to take his life into his own hands.  He wants a son, and He does what he can to get a son.
Tonight, I sat reflecting on this.  Am I trying to do things on my own, or am I trusting God to lead me?  The world, my friends, all tell me to take action.  But as I pray, I do not feel that leading from God, so does that mean to wait?  Or am I being lazy?  Where is the line?
I have an idea that I am getting excited about, but I wonder if I should follow through, or if it is just my human excitement.  I'm trying to pray for discernment.  I asked a friend, and she thought it sounded great, and in theory, I think it sounds great, but it could also be a disaster.  Okay, really, it wouldn't be a disaster, I just don't know if it's as good as an idea played out as it is as a dream.
But I guess, either way, it's fun to dream!
So is this one of those times that I wait, I pray, or is God just saying..."I don't know!  Surprise me!"
I don't know.
