Sleeping

Why did God invent sleeping? Why couldn't we all be robots to keep going and going and going like the Energizer bunny so we can accomplish what we want to? God didn't need to rest....why do I....if I was created in His image? I really think that's why we need to rest, because He did step back on the 7th day. Because he knew that ever since the fall, things were subject to friction and so parts wear down and need refreshment. That is what rest is for. Personally I look forward to Saturdays to sleep in...because the work week is so long!!! Thank You Father for sleep. Thank You Father for rest.
