9. What promise does Romans 8:21 hold out for mankind?

⁹ These with earthly hopes are now eagerly waiting for the time when the human creation will be “set free from enslavement to corruption.” (Romans 8:21) That emancipation will begin after Christ and his heavenly armies bring the great tribulation to a close by means of the Armageddon climax. This will mean the destruction of Satan’s entire wicked system of things, to be followed by the blessings of the Thousand Year Reign of Christ in Kingdom power.​—Revelation 19:17-21; 20:6.

Marvelous Freedom Ahead

11. What marvelous freedom will be enjoyed by survivors of the great tribulation?

¹¹ After the great tribulation, with its Armageddon climax, has cleansed the earth of wickedness, no longer will Satan the Devil be “the god of this system of things.” No longer will worshipers of Jehovah have to contend with Satan’s vile influence. (2 Corinthians 4:4; Revelation 20:1, 2) No longer will false religion misrepresent Jehovah and serve as a divisive influence on human society. No longer will servants of the true God experience injustice and exploitation at the hands of human authorities. What marvelous freedom will be enjoyed!

12. How will all be freed from sin and its effects?

¹² As “the Lamb of God that takes away the sin of the world,” Jesus will apply the value of his sacrifice to cancel out the sins of mankind. (John 1:29) When Jesus was on earth and forgave a person’s sins, he healed the forgiven one as proof of it. (Matthew 9:1-7; 15:30, 31) In like manner, Christ Jesus, as heavenly King of God’s Kingdom, will miraculously heal the blind, the speechless, the deaf, the physically maimed, the mentally afflicted, and those with any other sickness. (Revelation 21:3, 4) All obedient ones will get “sin’s law” nullified so that their thoughts and actions will be pleasing, both to themselves and to God. (Romans 7:21-23) By the end of the Millennium, they will have been brought to human perfection, in the ‘image and likeness’ of the only true God.​—Genesis 1:26.
