When Jesus returns, everything will become good, and even much better throughout the Millennium. He is coming to make all things new. For this reason, we should really love His return and sincerely pray for His kingdom to come just as He taught us (Matthew 6:10).
When Jesus returns, we shall thereafter live with Him forever and ever, together with our loved ones and all the saints since Adam. “For the Lord Himself will descend from heaven with a shout, with the voice of an archangel, and with the trumpet of God. And the dead in Christ will rise first. Then we who are alive and remain shall be caught up together with them in the clouds to meet the Lord in the air. And thus we shall always be with the Lord.” (1 Thessalonians 4:16-17)
In living forever and ever with Jesus, all the resurrected saints, and the ones who will still be alive at His coming, shall receive glorious immortal bodies (like that of Jesus) that will never never experience any kind of suffering. “For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ, who will transform our lowly (mortal) body that it may be conformed to His glorious (immortal) body” (Philippians 3:20). “There shall be no more death, nor sorrow, nor crying. There shall be no more pain” (Revelation 21:4).
Jesus’ return will also be the end of all evil leaders and evil leadership. The Devil, who is now the god of this world (2 Corinthians 4:4) and is responsible for all evil, will be bound and cast away when Jesus returns. Then our righteous Lord will reign on the earth, and we His righteous people, in our immortal bodies, shall reign with Him. “Then I saw an angel coming down from heaven, having the key to the bottomless pit and a great chain in his hand. He laid hold of the dragon, that serpent of old, who is the Devil and Satan, and bound him for a thousand years; and he cast him into the bottomless pit, and shut him up, and set a seal on him . . .Blessed and holy is he who has part in the first resurrection (at the rapture). Over such the second death has no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years,” (Revelation 20:1-3, 6).
Many of you have labored in so many different ways for the cause of Jesus. I have good news for you: When Jesus returns, He will not come empty-handed. For He said, “Behold, I am coming quickly, and My reward is with Me, to give to every one according to his work,” (Revelation 22:12).
These and more (e.g. Jesus destroying the haters of Israel and the Jews) are the reasons why we ought to love the return of the Lord. He is coming to make all things new. That is why we should in sincerity pray, “Thy kingdom come” (Matthew 6:10). But seriously, why would a spiritually sober person, in their right mind, not want Jesus to return quickly?
God bless you.
