Brother, according to Hebrews 3 and 4, we keep God's "rest" holy by entering the Sabbath at the appointed time and not entering any other time. The "rest" spoken of in
Hebrews 3 and 4 "has been ready since He made the world". God did not give them this "rest" for 40 years with Manna, them keeping a seventh day Sabbath from morning to morning which was correct in Eden, but not near the Promised Land until they reached the Promised Land and kept a Sabbath from evening to evening that is not a day of the week as defined in Genesis from morning to morning and confirmed below, because the Sabbath remembered is in the time zone of Eden.
long after the Sabbath (evening), as it dawns beyond Saturday (morning), came Mary Magdalene and the other Mary, to see the tomb. (Mathew 28:1, my own translation)
Although God gave them His Sabbath in the Promised Land, under Joshua they did not understand the "rest" of God's Sabbath to keep the Sabbath outside the time zone of the Promised Land. To correct this misunderstanding since Joshua, "God set another time for entering His rest, and that time is today", in the new covenant with the call in
Hebrews 3 and 4 to keep God's true Sabbath "rest". The "rest" that God wants us to enter "today", in the new covenant when believers find themselves living outside the time zone of the Promised Land, "has been ready since He made the world".
For if Joshua had given them rest, God would not have spoken later about another day. There remains, then, a Sabbath-rest for the people of God; for anyone who enters God’s rest also rests from their works, just as God did from his. Let us, therefore, make every effort to enter that rest, so that no one will perish by following their example of disobedience. (Hebrews 4:8-11 NIV)
United in our hope for the soon return of Jesus, Jorge
