After the kings and the merchants, it is the mariners who mourn, and in much the same terms. Mariners were at the bottom level of society and yet they also mourn the loss of Babylon.
‘And they cast dust on their heads, and cried, weeping and wailing, saying, Alas, alas, that great city.’ The mourners are like those who have suffered bereavement; they cannot stop repeating again and again their great sorrow at their sense of loss. Again, it is the suddenness of her end that appals them. They cannot understand how something that seemed so substantial could disappear so quickly. God removes her in this way to show that actually, she was always transient. Therefore believers should not fear man or the worst that man can do, for God is able to remove what seems invincible to us in a moment. As believers we have been placed in a situation where the powers of this world seem to tower over us. As individuals we do not possess the ability to resist them. God need not have made things this way, but he has done so deliberately to teach us to trust him. We cannot do anything in our own strength to defeat our earthly enemies let alone our spiritual enemies, yet God will remove them in an hour.
