God is in control.

…I have set my bow in the cloud, and it shall be a sign of the covenant between me and the earth…and the waters shall never again become a flood to destroy all flesh. (from Genesis 9)
And about the fourth watch of the night he came to them, walking on the sea. …they all saw him and were terrified. But immediately he spoke to them and said, “Take heart; it is I. Do not be afraid.” (from Mark 6)
