Exodus 12:13 And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and the plague shall not be upon you to destroy you, when I smite the land of Egypt.
[Patriarchs & Prophets pp 278>279] Before obtaining freedom, the bondmen must show their faith in the great deliverance about to be accomplished. The token of blood must be placed upon their houses, and they must separate themselves and their families from the Egyptians, and gather within their own dwellings. Had the Israelites disregarded in any particular the directions given them, had they neglected to separate their children from the Egyptians, had they slain the lamb, but failed to strike the doorpost with blood, or had any gone out of their houses, they would not have been secure. They might have honestly believed that they had done all that was necessary, but their sincerity would not have saved them. All who failed to heed the Lord's directions would lose their first-born by the hand of the destroyer.
By obedience the people were to give evidence of their faith. So all who hope to be saved by the merits of the blood of Christ should realize that they themselves have something to do in securing their salvation. While it is Christ only that can redeem us from the penalty of transgression, we are to turn from sin to obedience. Man is to be saved by faith, not by works; yet his faith must be shown by his works. God has given His Son to die as a propitiation for sin, He has manifested the light of truth, the way of life, He has given facilities, ordinances, and privileges; and now man must co-operate with these saving agencies; he must appreciate and use the helps that God has provided—believe and obey all the divine requirements.
As Moses rehearsed to Israel the provisions of God for their deliverance, “the people bowed the head and worshiped.” The glad hope of freedom, the awful knowledge of the impending judgment upon their oppressors, the cares and labors incident to their speedy departure—all were for the time swallowed up in gratitude to their gracious Deliverer. Many of the Egyptians had been led to acknowledge the God of the Hebrews as the only true God, and these now begged to be permitted to find shelter in the homes of Israel when the destroying angel should pass through the land. They were gladly welcomed, and they pledged themselves henceforth to serve the God of Jacob and to go forth from Egypt with His people.
Exodus 12:28 And the children of Israel went away, and did as the Lord had commanded Moses and Aaron, so did they. 29 And it came to pass, that at midnight the Lord smote all the firstborn in the land of Egypt, from the firstborn of Pharaoh that sat on his throne unto the firstborn of the captive that was in the dungeon; and all the firstborn of cattle.
May God add His blessing to the study of His word. "Good night" and God bless!
