The Church of God the Eternal has a word of warning to those COG members and lapsed members who do not keep every jot and tittle of the organizational rules and dogmas. God is going to get you for that!
We also have kept the Night to Be Much Observed. It is a perpetual memorial that we are commanded to observe (Exodus 13:9), and in doing so, God says that it shall be a sign. Strong's Concordance describes that sign as "a distinguishing mark." Surely it was a sign of obedience so that when the death angel passed over the children of Israel, they were protected. Every other family in Egypt suffered loss of life. So in our day, those called who continue not to participate in God's appointed places under that same sign of obedience likewise will suffer loss of life. However, this time it is their opportunity for spiritual life at stake.
As a called out Church of God member you were predestined to join the group and are required to keep all the days commanded. By doing so you get to be a god where you can rule with that rod of iron with vengeance!
After the Passover, God immediately initiated their journey out of sin. And for those that God had made choice to bring out, it was a night to be much observed. So also for us, for whom God did predestinate to be called in our time to have the opportunity to become one of the future Sons of God, it was a night to be much observed.
