Mark 4:40 And he said unto them, Why are ye so fearful? how is it that ye have no faith?
They might be in a boat in the middle of a storm but He doesn’t understand why they are afraid. If they know Him and are with Him why would they be afraid? If they understood His power and purpose would they be afraid?
Fear is a tool of Satan. Satan loves to have us living in fear and doubting God’s love and protection. God loves us and will take care of us. We can trust Him. He will meet our needs. When we understand Him more and what He has promised we will be able to live with less fear.
The biggest fear you should have is what will happen in eternity. If you are ready for death then you are ready for life.
