What is faith?

Maybe having faith is about believing what Christ says about my life here on earth, and how I am to spend it, and use it and give it up, and actually choosing to believe Him. To decide that I so firmly believe what Christ said, that I am going to live as though it were true. As though giving up my life, my resources, my hopes, my dreams, my direction, my decisions, my finances.... as though giving all that up and spending my life on Christ, really will be worth it. Believing it when Jesus said it would be worth it, it would be better, he was better, he is all I need. That in fact, I so firmly believe it, that I am going to live my life as though it were true. Maybe that's what faith is.
