It is not right to question why we celebrate Easter, because from the time of the Israelites, God has instructed His people to observe special feasts in His honor. These celebrations were established by God and their purpose has remained unchanged.
In Exodus chapter 12, God spoke to Moses and Aaron while they were still in Egypt. He declared that the current month would be the beginning of months, making it the first month of their year.
God commanded that on the tenth day of that month, each household should select a lamb according to their family size. If a family was too small, they could share with a neighbor. The lamb must be perfect, a male in its first year, taken from the sheep or goats.
They were also instructed to eat the meal in readiness—fully prepared and alert—because it was the Lord’s Passover.
Passover is one of the important feasts of Israel. It later became known as “Pascha,” a name still used by some Christian groups. The Israelites observe it every year at sunset on the 14th day of the first month, called Abib or Nisan.
This instruction was given before God delivered His people from Egypt, where they had lived for 430 years. Through this, God separated them and established a lasting remembrance of their deliverance.
