Read James 2
“Thus also faith by itself, if it does not have works, is dead.”
Verse 19 says that even demons believe, but they also tremble. You see, true faith has corresponding action. Mark's gospel Chapter 2, tells of four men bringing a paralytic man to be healed by Jesus. They couldn’t get through the large crowd, so they climbed the roof and made a hole in it to let the man down to Jesus.
Mark 2:5 says, “when Jesus saw their faith...” They said nothing, but their faith had action that Jesus "SAW”. Their friend was healed!
Faith does speak and declare, but there will be times when you have said all you can say. It’s time then to just keep believing and moving forward!
