Rest is not the cessation of activity. Rest is operating from a position of legitimately delegated authority and doing nothin in your own strength. You are free to function according to the terms and condition of your authority because the One whose authority was delegated to you guarantees the outcome, so long as you function within the scope of the authority.
Hebrews 4:9-11 “There remains therefore a rest for the people of God. For he who has entered His rest has himself also ceased from his works as God did from His. Let us therefore be diligent to enter that rest, lest anyone fall according to the same example of disobedience.”
Deut 5:12Keep the sabbath day to sanctify it, as the LORD thy God hath commanded thee. 13
Six days thou shalt labour, and do all thy work: 14But the seventh day is the sabbath of the LORD thy God: in it
thou shalt not do any work, thou, nor thy son, nor thy daughter, nor thy manservant, nor thy maidservant, nor thine ox, nor thine ass, nor any of thy cattle, nor thy stranger that is within thy gates; that thy manservant and thy maidservant may rest as well as thou.
Num 3:13
Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast:
mine shall they be: I am the LORD.
1 Peter 3:7Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and
as being heirs together of the grace of life; that your prayers be not hindered.
Tasks from a slave master is unrelenting. Under the pharaoh, work was slavery and unremitting. Today our worries are our taskmaster. Firstborn males (unblemished of the flock) are forbidden to work and are free to do what they do for a year as they are the property of God. Rest is freedom from your taskmaster.
In keeping the Sabbath, all will be firstborn and heirs to God. Rest is the freedom from the taskmaster so you may commune with God and Jesus the Master of the Sabbath. Keeping it Holy.
