The night is coming when no one can work. 

Blessed are the dead who die in the Lord from now on. They may rest from their labors, and their works follow them. § There the wicked cease from troubling, and there the weary are at rest.  § Now Samuel said to Saul, “Why have you disturbed me by bringing me up?”Whatever your hand finds to do, do it with your might; for there is no work or device or knowledge or wisdom in the grave where you are going. § The dead do not praise the Lord, nor any who go down into silence.I am already being poured out as a drink offering, and the time of my departure is at hand. I have fought the good fight, I have finished the race, I have kept the faith. Finally, there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will give to me on that Day.There remains therefore a rest for the people of God. For he who has entered His rest has himself also ceased from his works as God did from His.
