In Isaiah and Revelation, it is clear that we’ll be keeping the Sabbath again. It seems to me that if a commandment is valid before the fall, is validated during our fallen state and is also validated after we are fully redeemed,...,it was never suspended.
The Sabbath reinstated during the Tribulation is not valid because the work of Christ is not yet complete. It is observed in conjunction with Temple built during the Tribulation and is therefore not recognized. The Sabbath that is observed AFTER the Tribulation is the one reinstated by the Kingship of Christ and IS recognized.
You are mixing up your scriptures to try and prove your point and in doing so your errors are very apparent.
Oh?Post the verses and we see how 'clear' it is.
