The Passover, the Red Sea and the Jordan River

All three are types of the cross of Christ, but in different aspects: The Passover shows us the cross of Christ as a shelter from the judgment of God, and it shows that only the blood of a lamb (a look ahead to the perfect Lamb of God) can ensure that shelter. God judged Egypt and kept Israel safe. Atonement was made.
The Red Sea emphasizes our redemption. Exodus 15:13 says, "Thou in Thy mercy has, led forth the people which Thou last redeemed." This is the Savior-God whose people have nothing to do but stand still and observe their deliverance. And in so doing they come out on the other side of the sea safe and sound, a type of Christ's death and resurrection for us. The safe pathway for the redeemed becomes the grave for the Egyptian army.
The Jordan River signifies death in another way; this time it is the end of man in the flesh, and, at the same time, the end of Satan's power. "By grace are ye saved through faith; and that not of yourselves: it is the gift of God" (Eph. 2:8). At the Red Sea the children of Israel saw the enemy behind them slain on the seashore. At the Jordan the enemy is in front of them. But the enemy does not swing into action until after they had crossed into the Land. So with us; it is only when we try to lay hold upon the fullness of the promises that Satan gets busy. But there is full power at our disposal to disperse the enemy and live in the territory of the promises of God.
