Faith is so simple.
There is nothing more to it than trusting in God rather than in ourselves. You can never say to God, I have a right to expect this of you because I have done that for you. We like to think that we deserve what we get. We like to pay our way, but it is all quite pointless if we are dealing with God. There is a way to accept our place with God without feeling that we have to earn it, and that is what Paul was writing about in his letter to the Romans.
