All of these plagues, which culminate in this final and most devastating plague—the death of the firstborn—while directed at the Egyptians, constitutes God's condemnation, not only of the Egyptian religious system, but of the underlying condition of all of sinful humanity. The Pharaoh exalted himself above the people, and was considered to be a god. He was a central figure in the lives of the Egyptian people. This position was passed on from father to son, thereby perpetuating this systematic deception through each succeeding generation. This prideful arrogance is of the same spirit as Lucifer's, whose heart lusted after the throne of the very God Himself. This same spirit continues to work to promote this deception, in various forms, through the lives of the unbelieving and disobedient. … the whole world lies under the sway of the wicked one. (1 John 5: 19).
The night in which the Lord struck down the firstborn became known as the passover, and was to be a solemn observance to all Israel for all generations. God gave instructions to the children of Israel that each family should keep a lamb without blemish, kill it, and put the blood on the door posts of their houses. When the Lord sees the blood, He will passover that house, and the plague would not come to them. All of this is a wonderful vision of the plan of redemption and deliverance that God provides for each of us. That which is born of Adam must die, but the firstborn of God will be free and live. Jesus is our passover lamb, giving us life and hope. His blood cleanses us from all unrighteousness as He imparts His spirit within us, making us sons of God. May we all acknowledge and humbly submit to God's authority over us today. He is God, and we are not. Glory, honor, and power are His forevermore!
