If God is for us, who cares who's against us.

(Forgive me for my run-on sentences. I'm not fixing them. I'm beyond tired.)
Today in church and Sunday School we talked about Romans 8:31-39. It was so challenging. Dean spoke in Sunday School. He is a gifted speaker. I miss hearing him every Wednesday night. Anyways, he gave a great analogy.
I've personally never seen "Cinderella Man" but Dean said that the main character is a gifted boxer but then the depression hits and he has to quit. Later his agent comes back to him and convinces him to get back into boxing. The boxer's wife is worried that her husband will get hurt and then the family will starve to death because he won't be able to work and it's still the Great Depression. So she marches on over to the agents house (which mind you is huge while the boxer family's house is a dump), bangs on his door, and yells at him.
" Open up the door, I know you're in there. Don't you dare get my husband to fight again. He'll get hurt and our family will be ruined. You don't care about us. You don't have our best interest in mind.Open up this door, I know you are in there."
She screams these type of things for a couple of minutes until the agent finally opens up the door and the wife is shocked to see that the house is completely and utterly empty and the agent's family is sitting at a card table sipping tea. She realizes that he has sold everything he owns to promote her husband's career.
Don't we do the same thing? We bang on God's door, demanding an answer for his actions.
"Open up, God, I know you're in there. You don't care about me. You aren't working things out for me. You don't love me. Open up, I demand an answer."
Then God opens up the door and we see the gaping, gnarly scar on his wrist. We look at his face for comfort only to find the nasty scars across his forehead and temple. We drop our heads in shame and look up as He turns to walk back in the house and we see his ripped up and scarred back and realize that God didn't hold anything back from us. "He who did not spare his own Son, but gave him up for us all—how will he not also, along with him, graciously give us all things?" (Rom 8:32)
The Pastor said that God gives us a Rolls Royce and we're worried he won't give us the floormats. God takes care of the sparrows of the field, don't you think he'll take care of us?

Question: If you're playing a pick-up game of basketball and Lebron James is on your team, then do you really care who is on the other team? You're going to win.

If God is on your team then who really cares who's on the other team?
