22:3 no more curse. The primeval curse (Genesis 3:17-19) will be completely lifted from the new earth (see notes on Revelation 20:11; 21:1,4-5).

22:3 serve him. Life in the new earth will be far more than mere rest and fellowship. There will be ample time for these also, as well as for harps and singing, but there will also be work to do. This work will no doubt be referenced in some appropriate way to our service here in this life (note Revelation 22:12), but will surely be satisfying and fruitful work. In an infinite universe, with an eternity of time, we can never run out of something to do!

22:4 they shall see His face. This is the last reference in the Bible to the face of Jesus Christ. We shall finally see Him face to face! The gospel writers frequently mention His face, but they never give a description. After His arrest and trial, the Roman soldiers “struck Him on the face” (Luke 22:64), apparently so severely and repeatedly that “His visage was so marred more than any man” (Isaiah 52:14). But when He comes again, and we see Him, we shall rejoice forever in “the light of the knowledge of the glory of God in the face of Jesus Christ” (II Corinthians 4:6).

22:4 their foreheads. Note Revelation 3:12; 7:3.
