You talk about having trust in the promises of God but you don't say what those promises are.

Our faith should be in God. We should trust God. We should trust that God knows what he's doing regardless of what's happening in our lives.

This is one of the best examples of faith in the New Testament:

(Mark 1:40-41 NIV) A man with leprosy came to him and begged him on his knees, "If you are willing, you can make me clean." {41} Filled with compassion, Jesus reached out his hand and touched the man. "I am willing," he said. "Be clean!"

Hebrews has this definition of faith:

(Hebrews 11:6 NIV) And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.
