We are afraid because we don't know what God knows. He knows we do not know. He says in Isaiah 55:8-11, His thoughts and ways are not ours; however, His Word never returns void. He knows who He is; we are ever learning to know Him and to trust him. We are to face the fear and do it anyway. Frankly, once we really begin to know God's ways; even the unthinkable makes sense as He is always proving that "nothing is impossible with God." Courage is always required in leaders and disciples because people are always watching and waiting to be amazed. As they watch the leaders, they grow confidence and the desire to follow the leader. It is the job of the leader to replicate themselves. Just as a child learn to do things by watching parents and older siblings, we learn by watching our leaders.
