The Bible does not tell us anything about people’s age in heaven or if we will even grow old. Scientifically adults reach their physical peak from their late 20’s to early 30’s. So, some suggest that the redeemed will be around the age of 30 since this is the age that Jesus started His ministry on earth. Others say that the age will be 33 since this is the age of Jesus’ Resurrection. It is obvious that babies that died on earth will grow to adulthood in heaven and the old saints will be given youthful bodies. So, eventually everyone would reach the same age.
The apostle John tells us, “Dear friends, now we are children of God, and what we will be has not yet been made known. But we know that when He appears, we shall be like Him, for we shall see Him as He is” (1 John 3:2). This refers to the fulfillment of God’s plan for fallen man—restoration to the divine image. Man was made in the image of God (Gen. 1:26), but sin ruined that likeness. It is God’s design to restore that resemblance by giving to man victory over sin and over every temptation (Rom. 8:29; Col. 3:10).
This restoration takes place at the second advent. Paul wrote, “Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed— in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality” (1 Cor. 15:51–53; Phil. 3:20, 21).
And the apostle summarizes the saints’ future glorified condition saying, “Eye has not seen, nor ear heard, nor have entered into the heart of man the things which God has prepared for those who love Him” (1 Corinthians 2:9). What God has prepared for the redeemed is far beyond anything that men may now know beside the gospel of Christ (Isa. 64:4).
