The Bible tells us that this old world will end at Armageddon soon.
God’s war of Armageddon will actually prevent the destruction of all mankind. Jehovah created the earth to be inhabited, not destroyed in a thermonuclear war among humans or otherwise rendered unfit for life. (Isaiah 45:18)
He will “bring to ruin those ruining the earth.” (Revelation 11:18) But the psalmist declared: “Jehovah himself has become king. The productive land [Hebrew, te·vel?; the earth, as fertile and inhabited, the habitable globe] also becomes firmly established so that it cannot be made to totter.”—Psalm 96:10.
Armageddon will be fought because God is righteous and will no longer tolerate evil. (Psalm 11:7) Satan the Devil’s organization, comprising both demons and rebellious humans, responsible for millenniums of wickedness and woe, must therefore be destroyed. (Compare Genesis 3:15.)
Jehovah’s universal sovereignty will be upheld at Armageddon, and that war will clear his name of the reproach heaped upon it for centuries. As God declared through his prophet Ezekiel: “I shall no more let my holy name be profaned; and the nations will have to know that I am Jehovah.”—Ezekiel 39:7.
What God does at Armageddon will be in complete harmony with his principal attributes of justice, wisdom, power, and love. (Deuteronomy 32:4; Job 12:13; Isaiah 40:26; 1*John 4:8) He will act against “ungodly sinners,” not against the upright. (Jude 14,*15) Only ‘the wicked ones will be given to the sword.’ (Jeremiah 25:31) This will pave the way for the restoration of Paradise, fulfilling the divine purpose for the earth and humankind.—Luke 23:43.
When will it happen?
Armageddon will occur at the conclusion of the Great Tribulation [ Matthew 24.21-30] When Jehovah rises up to defend his servants against Satan's and human governments' attack, Armageddon will be in progress!
Human governments will collapse. Flooding cloudbursts, devastating hailstones, streaking fire and sulfur, raging pestilences—truly acts of God—will cause world panic outside the ranks of Jehovah’s Witnesses. Their human foes will turn their weapons against their own ranks. And those whom this suicidal warfare does not kill off, Jehovah will annihilate.—Ezekiel 38:18-23; Daniel 2:44.
