Genesis 2:1 Thus the heavens and the earth were completed, and all their hosts. 2 By the seventh day God completed His work which He had done, and He rested on the seventh day from all His work which He had done. 3 Then God blessed the seventh day and sanctified it, because in it He rested from all His work which God had created and made.
When God ceased from His creative work, it wasn’t because He was tired. As Isaiah 40:28 explains: “Have you not known? Have you not heard? The everlasting God, the LORD, the Creator of the ends of the earth, neither faints nor is weary.”
Having spent six days preparing the earth for man’s physical needs, God was now establishing the seventh day of the week as a time during which man could rest from his physical labor and have his spiritual needs met. Genesis 2:3 explains that God “blessed” and “sanctified” the seventh day. As additional translations make clear, this means God made this day “holy” (New International Version and Bible in Basic English) and “set it apart as a special day” (Good News Bible) unlike any other day of the week.
If God rested on the seventh day, sanctified it, and made it holy, shouldn’t we continue to rest on the seventh day? God knew what He was doing by giving us a day of rest. We need to step back from all we do during the week, and truly “rest”, cease from working. This allows our bodies, minds, and souls to recover from all the stresses of the week and be refreshed in and focused on Him.
