And Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which He will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever…And the LORD said unto Moses, Stretch out thine hand over the sea, that the waters may come again upon the Egyptians, upon their chariots, and upon their horsemen. – Exodus 14:13,26

You have come up out of Egypt, O young believer, but the taskmasters are at your heels! There may come a decisive moment, after which they shall never pursue you again. These who seek your soul are to be destroyed, so that there shall not be one of them left. I believe that many a young convert hates sin, and hates all evil habits, but these evils keep dogging his footsteps and seem as if they would master him; and then there comes a time of great struggle and tremendous battling without and within: on that one desperate field he fights the matter out. His adversaries are drowned in that Red Sea: his old sins and his old habits lose for ever their former power. The Red Sea rolled between Israel and Egypt; and whatever else might trouble the pilgrim host, they were never, throughout the whole forty years, molested by Pharaoh, or any of the Egyptians. It is a grand thing when a man gets clean away from the world and is reckoned as dead to it. He has burnt his boats, and has landed on the shore, from which he never can go back again, but must fight out the battle against sin even to the end. When a man is sworn into the army of Christ for eternity, and the world has cast him out, there is nothing for him but to go right ahead. Everything that he has is now staked on the cross of Christ. Happy man to have come to such a pass- to be once for all crucified to the world, and the world crucified to him! The Egyptians of sin which had so fiercely pursued him are drowned, and the rest of the Egyptians of evil have given him up; and he may go on his way to the promised land in peace, so far as his old taskmasters are concerned. ~ C.H. Spurgeon
