God rested from His creative work! He took time to see what He have done and enjoyed it. We can take note of that! Yes, the Sabbath is HOLY. (Genesis 20:8-11) Yes it is set apart to not only rest in God and celebrate and worship Him, but also to rest with God . . . to take time to enjoy all He has accomplished in and through our work.
While man is to work, we all also called to rest. It makes sense for our health alone! However, when God actually does something, we are to do it as well. God calls us to take time out of the ordinary patterns of life to worship and to rest. We are to take a break from the labors of life and enjoy Him, His works, His glory, and yes, even our accomplishments.
Remember, it's ok to take a break on a regular basis as long as we are consistently working! Enjoy the weekend . . .remember God, remember to rest with Him and in Him!
