Your TASC board of directors has been reading through Jonathan Sarfati's The Genesis Account: A theological, historical, and scientific commentary on Genesis 1-11.
We have just finished chapters 11-12 which cover all of Genesis 2. This article was inspired by those chapters.
Genesis 2:1-3 (ESV):
1 Thus the heavens and the earth were finished, and all the host of them.
2 And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done.
3 So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
God had completed his creative work by day 7 of creation week. The processes He used to create during the first six days were different from those He now uses to sustain and uphold the universe (Col 1:16-17; Heb 1:1-12). God resting on the seventh day was obviously not from tiredness but reflected the completeness of His creative acts (Heb 4:10); He ceased (rested) from His creative activities. Ex 31:17 says God was refreshed on the seventh day, akin to our satisfaction after completion of a significant task.
