Did you read what UnitedWithChrist shared with you in post #28? So if Isaiah 66:23 teaches that we will keep the sabbath day in heaven, then it also teaches we will keep the new moon festival as well. "And it shall be from new
moon to new moon, and from sabbath to sabbath, all mankind will come to bow down before Me, says the Lord” - Isaiah 66:23. Let's be consistent.
If you insist on sabbath observances based on Isaiah 66:23, then you also need to observe
new moons as well. Yet from what I hear, most Sabbatarian’s don’t observe new moons. hmm.. That’s inconsistent. New moons require night, hence Sabbatarians have night in heaven Isaiah 66:23. Is there night and day in heaven? NO In Revelation 21; 23; 22:5 we read there is
no night in heaven. You cannot have "new moon to new moon" or "sabbath days" without day and night. Are new moons and sabbath keeping a requirement for Christians based on the New Covenant terms? NO.
*Colossians 2:16 - Therefore no one is to act as your judge in regard to food or drink or in respect to a festival or a
new moon or a Sabbath day 17 things which are a
mere shadow of what is to come; but the substance belongs to Christ.
Will there be Levital priests in the new heaven? If Isaiah 66:23 teaches that we will keep the sabbath day in the new heaven, then it also teaches in Isaiah 66:21 that the Levitical priests will be in the new heaven, because it is also mentioned. What happened to the Levitical priesthood under the new covenant terms?
Priesthood changed so did the law. Hebrews 7:12 - For when
the priesthood is changed, the law must be changed also. *The old and new covenants do not mix.
Why are you so obsessed with the sabbath? Do you believe that keeping the sabbath day is necessary for salvation? Where do you attend church?
