Yes, the Bible tells us repeatedly that someday Jesus Christ will return in glory—and when He does, life as we now know it will come to an end. The Bible calls this "the blessed hope— the glorious appearing of our great God and Savior, Jesus Christ" (Titus 2:13).
I suspect many people, however, feel the same way you do; they aren't sure they really want Jesus to return. Some are like you: They're satisfied with their life right now, and they don't want it to come to an end. Some may even be like the man in one of Jesus' parables, who said to himself, "You have plenty of good things laid up for many years. Take life easy" (Luke 12:19).
Others, however, dread the thought of Christ's return because they know they aren't ready. They have put off giving their lives to Christ, and they know if He were to come without warning (as the Bible promises), they would be lost. This is why the Bible warns us not to delay our commitment to Christ.
Listen: If you could glimpse heaven for just one minute—or even one second—you would never say again that this life is better. Yes, perhaps God has given you a good life, and you should thank Him for it. But heaven is far, far greater! Is your hope in Christ? Make sure of your commitment to Him, and then ask Him to help you "Set your (mind) on things above, not on earthly things" (Colossians 3:2).
