Israel was, in the first place, delivered from the hand of God, and then, as the result of this, Israel was delivered from the hand of Pharaoh.
Consider:
I. The state of the Israelites when Moses came to them. (1) They were in bondage. (2) They were so far conscious of the misery of their position that they had a strong desire for liberty. (3) They were by no means ready at first to accept the message of God's deliverance. (4) They had their comforts even in slavery. In all these things we have a picture of ourselves.
II. The deliverance. (1) The moment the Passover is observed, that moment Pharaoh's power is broken. The moment that all is right between us and God, that moment Satan's power is broken, and he can no longer hold us in bondage. (2) The waters of judgment which saved the Israelites were the means of destroying the vast host of Egypt. The power of Satan is broken by the very means by which he intended to destroy. (3) It is our privilege to take our stand on the other side of the Red Sea and see ourselves "raised up with Christ" into a new life.
