The disciples decided they should probably wake Jesus to see if He could help. Good call. Mark 4 records that after Jesus rubbed the sleep from His eyes, He "rebuked the wind and said to the waves, 'Silence! Be still!' Suddenly the wind stopped, and there was great calm. Then he asked (the disciples), 'Why are you afraid? Do you still have no faith?'"
When we are tossed about by the turbulence of doubt, when the waves of worry crash over lives , when the funnel clouds of fear threaten to sweep us away, Jesus' response is exactly the same as His response to the disciples on their stormy night: “Silence! Be still! Why are you afraid? Do you still have no faith?”
The very first thing we must do when our lives get stormy is to quiet our hearts before God. We must remind ourselves of just who He is. He offers a very pointed command in Psalm 46:10--“Be still and know that I am God.”
When we see and understand who God is we will know, beyond a shadow of a doubt, that He always has our best interests in mind. That He is completely worthy of our trust. That He is infinitely faithful to His children. That He is more than able to accomplish anything that comes our way.
When we believe at the core of our being that God is who He says He is, our fears will subside. There is no room for fear in a heart that is full of faith.
