Romans 10:17

So faith comes from hearing (what is told), and what is heard comes by the (preaching of the) message concerning Christ.

Are we hearing the message? We have been given a measure of faith by God. A starter seed that we are to develop and increase. The message of Christ is salvation to those who believe in faith that Jesus died for our sins. Without faith, it is impossible to please God, but we can move mountains with faith.
