So it came between the camp of the Egyptians and the camp of Israel. Thus it was a cloud and darkness to the one, and it gave light by night to the other, so that the one did not come near the other all that night. – Exodus 14:20

That same glory which lit up the canvas city, and made it bright as the day, darkened all the camps of Egypt. They could see nothing, for the dark side of God was turned to them. I am afraid it is so with some of you. Oh, dear friends, is it not a dreadful thing that to some men the most terrible thing in the world would be God? If you could get away from God, how happy, how merry, how jolly you would be! You want to depart from Him; you are departing from Him. One of these days Jesus will tell you to depart. “Keep on as you were,” says He, “you were always departing from God; keep on departing. Depart from Me, ye cursed!” That will be the consummation of your life. To some of us the thought of God is joy, but to the ungodly nothing would be such good news as to hear that there was no God, indeed, they find a dreadful comfort in endeavoring to be sceptical and unbelieving. God has a dark side to sinners; His justice and His righteousness, which are the comfort of His people, are the despair of the wicked.

Now look at the gospel itself. Why, there are many that sit and hear the gospel, and they say, “I do not understand this believing, this atonement, and so on.” No, I know you do not; you are an Egyptian, it is dark to you. It is a savor of death unto death to you. I am afraid you will go on quarrelling with it until God ends the quarrel in your destruction. Oh, that ye would believe in Jesus Christ! Oh, that ye would “kiss the Son, lest He be angry, and ye perish from the way, when His wrath is kindled but a little,” for “Blessed are all they that put their trust in Him.” You can come and be numbered with Israel, for the door into Israel is Christ Himself. If you come to Christ you have come to His people, you have come to safety, and henceforth “the Lord will go before you; and the God of Israel will be your rereward.” Amen. ~ C.H. Spurgeon
