4These are the feasts of the LORD, even holy convocations, which ye shall proclaim in their seasons.
5In the fourteenth day of the first month at even is the LORD’s passover.
6And on the fifteenth day of the same month is the feast of unleavened bread unto the LORD: seven days ye must eat unleavened bread.
7In the first day ye shall have an holy convocation: ye shall do no servile work therein.
Tonight is the last of the day of the Feast of Unleavened Bread (aka, Days of Unleavened Bread). When Israel came out of Egypt, they didn’t have time to allow for dough to rise, and so this feast was a commemoration of that. However, that was only one of its meanings, and there are indications that this feast existed before Israel went into Egypt.
Today, the Days of Unleavened Bread symbolize the putting out of sin from the life of a Christian and keeping it out. Seven is a number of a complete cycle. It is also the number of perfection. The seven days illuminate the fact that putting out sin and keeping it out is a lifelong learning process. Literally, perfection does not come in one day.
It is one of the “feasts of the LORD”. These are not Jewish feasts, they are not Armstrong feasts, they are not Church of God feasts, but they are the feasts instituted by God.
