mustard seeds

So we've all heard the story in Matthew 17 (14-21) about Jesus healing a demon possessed boy. There seems to be a sermon about this once a year at most churches- even in Costa Rican churches! And thats what the pastor at our church here preached about this week. But basically, the disciples can't rebuke a demon from this boy and they ask Jesus to and somehow Jesus could do it, but they couldn't. Then Jesus explains that in order to move mountains all we need is the faith the size of a mustard seed. A freaking mustard seed! And they couldn't rebuke the demon because they didn't have faith in God that they could do it. The pastor handed out mustard seeds and i took a picture of it in my bible. Look at the picture and look how tiny that is! Its hardly the size of the print in my mini bible. Its so small- and thats all we need in order to have true faith to do miracles. 
Now, I haven't seen any huge miracles in my life yet- but I know that I'm going to. Because I have faith in God and trust in him that he's going to do amazing things through me and through other people all over the world. All things are possible with God, I mean, he made the universe. So instead of asking yourself why i should trust God- you should be asking why aren't I trusting God?
