This month shall be unto you the beginning of months; it shall be the first month of the year to you. Exodus 12:2
We sing it with the children in the Sunday school: ‘Happy birthday to you, Only one will not do. Born again means salvation. How many have you?’ Just as the Lord Jesus told Nicodemus: ‘Ye must be born again’. Birthdays are important and they are joyfully celebrated. But the day of our natural birth is not nearly as important as the day of our spiritual birth. The first ushered us into physical life, the second ushered us into eternal life. It’s worth celebrating, just as the Israelites were instructed to celebrate the Passover.
We are unsure of the calendar that the children of Israel used before the Exodus, probably whatever calendar the Egyptians were using at that time. But with the Passover and the deliverance from Egypt came a new calendar that Jewish people have been using ever since. It marked a change in how they observed days and seasons, all of which revolved around their relationship to God. For Christians, we also have a new calendar, although it is not nearly as elaborate as the Hebrew calendar.
Unlike the Hebrew calendar with its many holy days and feasts throughout the year, our calendar has only one day, the first day of the week. Every week. Before He went to Calvary, the Lord Jesus instituted the feast we call the Lord’s Supper. And He told us to keep repeating it until He returns for us. The pattern established by the New Testament Christians is for the feast to be eaten on the first day of the week. And this we do, because what transpired at Calvary is the most important event in history, far beyond anything remembered in the Hebrew calendar.
This is the first day of the week. It is the day to remember the beginning of everything that is the most important to our Lord, and to us. -Jim MacIntosh
