Being afraid sometimes can cause us to be overwhelmed by circumstances, in so much that some people get overrun with fear; some end up in hospital/rehabilitation centers. But God is calling us to a life of faith.
The verse shows us that we should speak to the mountain. If a situation is constantly before you that it becomes a mountain, speak to it and by faith the situation will move.
Concealed faith is as dead as it is hidden. We believe so we speak, speak your faith.
