Benefits Of Rest

Rest allows your body to renew itself.  Waste products are removed, repairs are effected, enzymes are replenished, and energy is restored.

Rest aids in the healing of injuries, infections, stress, emotional traumas and other assaults on the body.

Rest strengthens the body’s immune system to protect and fight off disease.

And on the seventh day, God ended his work which he had made, and he rested on the seventh day from all his work which he had made. And God blessed the seventh day and sanctified it: because that in it he had rested from all his work which God created and made. Genesis 2:2-3 

My presence shall go with thee, and I will give thee rest.  Exodus 33:14 

For he spoke in a certain place of the seventh day on this wise, And God did rest the seventh day from all his works. And in this place again, if they shall enter into my rest. Seeing therefore it remaineth that some must enter therein, and they to whom it was first preached entered not in because of unbelief: Again, he limiteth a certain day, saying in David, today, after so long a time; as it is said, today if ye will hear his voice, harden not your hearts. For if Jesus had given them rest, then would he not afterward have spoken of another day. There remains therefore a rest to the people of God. For he that is entered into his rest, he also hath ceased from his own works, as God did from his. Let us labour therefore to enter that rest, lest any man fall after the same example of unbelief.  Hebrews 4:4-11

Those who make great exertions to accomplish just so much work in a given time and continue to labour when their judgment tells them they should rest, are never gainers. They are living on borrowed capital. They are expending the vital force which they will need at a future time. And when the energy they have so recklessly used, is demanded, they fail for want of it.
