God rested and made the day holy (set apart) for us.
The big problem for us is that we don't know how to rest. Too much time is spent escaping our problems through our headphones, TV sets and computer screens. We get rest, but after it - we are not more equipped to handle our problems and they are still there.
1 Peter 5:7 Give all your worries and cares to God, for he cares about you.
God is our rest and He invites us into His rest.
and lastly a word from Revelation 14 emphasis mine
9 A third angel followed them and said in a loud voice: “If anyone worships the beast and his image and receives his mark on the forehead or on the hand, 10 he, too, will drink of the wine of God’s fury, which has been poured full strength into the cup of his wrath. He will be tormented with burning sulfur in the presence of the holy angels and of the Lamb. 11 And the smoke of their torment rises for ever and ever. There is no rest day or night for those who worship the beast and his image, or for anyone who receives the mark of his name.” 12 This calls for patient endurance on the part of the saints who obey God’s commandments and remain faithful to Jesus.13 Then I heard a voice from heaven say, “Write: Blessed are the dead who die in the Lord from now on.”
“Yes,” says the Spirit, “they will rest from their labor, for their deeds will follow them.”
