And when Pharaoh drew near, the children of Israel lifted their eyes, and behold, the Egyptians marched after them. So they were very afraid, and the children of Israel cried out to the LORD… And Moses said to the people, “Do not be afraid. Stand still, and see the salvation of the LORD, which He will accomplish for you today. For the Egyptians whom you see today, you shall see again no more forever. – Exodus 14:10,13

We read that Israel lifted up their eyes and saw the Egyptians, and then they began to tremble, and cry out: and so God drew the blinds down that His poor children could not see their frightful taskmasters. It is a great mercy when God does not let us see everything. What the eye does not see, perhaps the heart will not rue. May I ask you just to try and use your eyes a little now? There are your sins; will you look back on them for a minute? Look steadily. They are quite as dreadful as the Egyptian horsemen and chariots. I have looked intently, and I cannot see a sin remaining. “What, have you lived such a life that you have never sinned?” Ah, no, beloved, I have to mourn over many offenses, but I cannot see one of them now, for my sin is covered. I believe this text, “The blood of Jesus Christ His Son cleanseth us from all sin.” If I am cleansed, why should I see spots, or speak as if I did? The Lord stands between His people and their sins. Jesus, who veiled His glory in the cloud of our humanity, interposes between us and our transgressions. Is it not written, “The iniquity of Israel shall be sought for, and there shall be none; and the sins of Judah, and they shall not be found; for I will pardon them whom I reserve”? If God declares that our sins cannot be found, then I am sure we need not look for them; and if He says that Christ has made an end of sin, then there is an end of it. The Egyptians shall not come near us all the night of this life; and when the morning breaketh, we shall see them dead upon the shore. Then shall we sing unto the Lord, for He hath triumphed gloriously, and our transgressions and iniquities hath He cast into the depths of the sea. ~ C.H. Spurgeon
