35That day when evening came, he said to his disciples, "Let us go over to the other side." 36Leaving the crowd behind, they took him along, just as he was, in the boat. There were also other boats with him. 37A furious squall came up, and the waves broke over the boat, so that it was nearly swamped. 38Jesus was in the stern, sleeping on a cushion. The disciples woke him and said to him, "Teacher, don't you care if we drown?" 39He got up, rebuked the wind and said to the waves, "Quiet! Be still!" Then the wind died down and it was completely calm. 40He said to his disciples, "Why are you so afraid? Do you still have no faith?" 41They were terrified and asked each other, "Who is this? Even the wind and the waves obey him!"
being afraid of circumstances
10 So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand. 13 For I am the LORD, your God, who takes hold of your right hand and says to you, Do not fear; I will help you.
28And we know that in all things God works for the good of those who love him, who have been called according to his purpose.
8 If I go up to the heavens, you are there; if I make my bed in the depths, you are there. 9 If I rise on the wings of the dawn, if I settle on the far side of the sea, 10 even there your hand will guide me, your right hand will hold me fast.
