Jesus had taught very clearly in John 10:10, 27,28: ‘I came that they may have life and have it abundantly. My sheep hear my voice and I know them, and they follow me. I give them eternal life and they will never perish.’
The Book of Revelation later reveals to us about the end times of this world to see the culmination of his divine work in 21:9, 10, 23, 25, 26, 27. ‘Then came one of the angels…and he carried me away…and showed me the holy city Jerusalem coming down out of heaven from God…and the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb… and there will be no night there. They will bring into it the glory and the honor of the nations. But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb’s book of life.’
Further, in chapter 22: 3-5,7,12,13 ‘No longer will there be anything accursed, but the throne of God and of the Lamb will be in it, and his servants will worship him. They will see his face, and his name will be on their foreheads. And night will be no more. They will need no light of lamp or sun, for the Lord God will be their light, and they will reign forever and ever. And behold, I am coming soon. Blessed is the one who keeps the words of the prophesy of this book. Behold, I am coming soon, bringing my recompense with me, to repay each one for what he has done. I am the Alpha and the Omega.’
