Matthew 6:14-16

14 "In prayer there is a connection between what God does and what you do. You can't get forgiveness from God, for instance, without also forgiving others.

15 If you refuse to do your part, you cut yourself off from God's part.

16 "When you practice some appetite-denying discipline to better concentrate on God, don't make a production out of it. It might turn you into a small-time celebrity but it won't make you a saint.
