"And when he got into the boat, his disciples followed him. And behold, there arose a great storm on the sea, so that the boat was being swamped by the waves; but he was asleep. And they went and woke him, saying, “Save us, Lord; we are perishing.” And he said to them, “Why are you afraid, O you of little faith?” Then he rose and rebuked the winds and the sea, and there was a great calm. And the men marveled, saying, “What sort of man is this, that even winds and sea obey him?” (Matthew 8:23-27)
This narrative, gives us an example of faith and unbelief, in order that we may learn how mighty the power of faith is, and that it of necessity has to do with great and terrible things and that it accomplishes nothing but wonders; and that on the other hand unbelief is so fainthearted, shamefaced and trembling with fear that it can do nothing whatever. An illustration of this we see in this experience of the disciples, which shows the real state of their hearts. First, as they in company with Christ entered the ship, all was calm and they experienced nothing unusual, and had anyone asked them if they believed, they would have answered, Yes. But they were not conscious of how their hearts trusted in the calm sea and the signs for fair weather, and that thus their faith was founded upon what their natural eyes saw. But when the tempest comes and the waves fill the boat, their faith vanishes; because the calm and peace in which they trusted took wings and flew away, therefore they fly with the calm and peace, and nothing is left but unbelief.
But what is this unbelief able to do? It sees nothing but what it experiences. It does not experience life, salvation, and safety; but instead the waves coming into the boat and the sea threatening them with death and every danger. And because they experience these things and give heed to them and turn not their fear from them, trembling and despair can not be suppressed. Yes, the more they see and experience it the harder death and despair torment them and every moment threatens to devour them. But unbelief cannot avoid such experiences and cannot think otherwise even for a second. For it has nothing besides to which it can hold and comfort itself, and therefore it has no peace or rest for a single minute.
Therefore, God bestows faith to the end that it should deal not with ordinary things, but with things no human being can master as death, sin, the world, and Satan. For the whole world united is unable to stand before death, but flees from and is terrified by it, and is also conquered by it; but faith stands firm, opposes death that devours everything, and triumphs over it and even swallows the insatiable devourer of life. In like manner, no one can control or subdue the flesh, but it reigns everywhere in the world, and what it wills must be done, so that the whole world thereby is carnal; but faith lays hold of the flesh and subdues and bridles it, so that it must become a servant. And in like manner no one can endure the rage, persecution, and blasphemy, infamy, hatred, and envy of the world; every one retreats and falls back exhausted before it, it gets the upper hand over all and triumphs, and if they are without faith it mocks them besides and treads all under its feet and takes pleasure and delight in doing so.
The heart so severely experiences in this battle sin and death, the flesh, Satan and the world, that it has no other thought than that it is lost, that sin and death have triumphed, and that Satan holds the field of battle. The power of faith however experiences but little of that. This is set forth in our narrative, when the waves not only dashed into the boat, but even covered it, so that it was about to go under and sink, and Christ was lying asleep. Just then there was no hope of life, death had the upper hand and had triumphed; life was lying prostrate and was lost.
This story is a comforting example and doctrine, how we should conduct ourselves, so that we may not despair in the agony of sin, in the peril of death, and in the tumult of the world; but be assured that we are not lost, although the waves at once overwhelm our little boat; that we will not perish, although we experience in our evil conscience sin, wrath, and the lack of grace; that we will not die, although the whole world hates and persecutes us, although it opens its jaws as wide as the rosy dawn of the morning. These are all waves that fall over your little bark, cause to despair, and force you to cry out: “Save us, Lord; we are perishing.”
