What does Revelation 22:3 mean?
Adam's sin brought the curse of laborious work and death on the human race. When Adam sinned, God told him: "Cursed is the ground because of you; in pain you shall eat of it all the days of your life; thorns and thistles it shall bring forth for you; and you shall eat the plants of the field. By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return" (Genesis 3:17–19).This curse will not apply to life in the eternal state, and life will be blissful and productive. The throne of God and the Lamb will be in the eternal city, and God's people will serve and worship God. Service for God is never fruitless if we serve Him with gladness and rely on Him for the results. Paul told the Corinthians, "…in the Lord your labor is not in vain" (1 Corinthians 15:58).
