I'm sure I've written about this before. This is about Israel just before God delivered them out of Egypt. They were instructed by God, through Moses and Aaron, to do some things. Although it speaks of a celebration, the Passover, the everlasting ordinance that would be between God and His people, it is clear that it is the everlasting ordinance between God and "whosoever will" believe in the Lord Jesus Christ to be saved and have everlasting life.
And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up, that whoever believes in Him should not perish but have eternal life. (John 3:14-15)
Ordinance: An action prescribed, statute.
This ordinance speaks of a feast, which the Jewish people still celebrate, in remembrance of that day thousands of years ago. I'm sure you know the story. Each family was to kill a spotless lamb, apply the blood to the doorposts and lintels of their home, then roast the meat and eat all of it...or if there was any remaining, burn it. The angel of the Lord would come later and kill all the firstborn of every Egyptian household, both man and beast. It would be brutal. But none of the people of Israel would be touched because of that blood on the doorposts of the homes of the Jews. It was an everlasting ordinance between God and His people.
They would be set free from their captivity in Egypt. They would then be led to the land which God had already set aside for them.
Our salvation is like this. We receive Christ, through the blood of our spotless Lamb of God, and through Him alone we are set free from the slavery of the world's clutches (Egypt). Through this sacrifice of His life for ours...and then ours for Him...we have entered into a new birth, new life, new land that God has promised to those who believe.
However, if one has not applied that blood to the doorposts of their heart, it will not happen. It is a heart matter. It is not an intellectual knowing of who Jesus is, but a heart knowing of Him. We recognize and regret our sins, repent of them and thank Him for His wonderful act of love on that cross for each of those "whosoever will" receive Him.
We can proclaim each day the salvation that saved us from the evil one who wishes to daily take control of our lives. We become part of the very same everlasting ordinance. We claim the right to say we are the children of God, not by the good things we do but by the very sacrifice of that spotless Lamb of God. Not our plan for salvation, but God's plan for mankind's salvation.
Is that blood of the Lamb over your heart? Have you decided to give your life to the One who gave His? It's the only way it can be done. Remember...it can be an everlasting ordinance, something God requires. Yet His requirements are for our good...for our life everlasting. Won't you consider it. Won't you share the idea with your friends and family?
Exodus 12:23-24 - For the LORD will pass through to strike the Egyptians; and when He sees the blood on the lintel and on the two doorposts, the LORD will pass over the door and not allow the destroyer to come into your houses to strike you. And you shall observe this thing as an ordinance for you and your sons forever.
