"Take heart; it is I. Do not be afraid."

Commenting on Mark 6:47-52, William Barclay writes:

It is the simple fact of life, a fact which has been proved by countless thousands of men and women in every generation, that when Christ is there the storm becomes a calm, the tumult becomes a peace, what cannot be done is done, the unbearable becomes bearable, and men pass the breaking point and do not break. To walk with Christ will be for us also the conquest of the storm.
