No, but this seems to concern some believers. Author Randy Alcorn, in his book Heaven, deals with this question.

A man wrote me expressing his fear of losing his identity in Heaven: “Will being like Jesus mean the obliteration of self?” He was afraid that we’d all be alike, that he and his treasured friends would lose their distinguishing traits and eccentricities that make them special.

But he needn’t worry. We can all be like Jesus in character yet remain very different from each other in personality. Distinctiveness is God’s creation, not Satan’s. What makes us unique will survive. In fact, much of our uniqueness may be uncovered for the first time.

At the very end of Mere Christianity, C. S. Lewis writes, “Until you have given up your self to Him you will not have a real self. Sameness is to be found most among the most ‘natural’ men, not among those who surrender to Christ. How monotonously alike all the great tyrants and conquerors have been: how gloriously different are the saints. . . . Nothing in you that has not died will ever be raised from the dead. Look for yourself, and you will find in the long run only hatred, loneliness, despair, rage, ruin, and decay. But look for Christ and you will find Him , and with Him everything else thrown in.”

There is a profound lesson here. The more like Christ we become, or the more we approach the good, the true, and the beautiful, the more unique, fascinating, and special we become. The farther away we move from Christ, or the more we move toward the evil, the false, and the ugly, the more dull and monotonous we become.

God brings out the best in us, and so we can never reach our full, glorious potential away from Him.

Perhaps you’ve heard the saying, “Christians are so heavenly minded they’re no earthly good.” The idea behind this statement is supposed to be that Christians are content to leave the world the way it is because we are simply biding our time here so that we can get to our final destination, Heaven. It’s only those people who don’t believe in Heaven that will do the hard work to improve the Earth, because Earth is all there is.

While this is a catchy cliché, it misses an important point. Christians do try to make the Earth a better place, every single day, and they do it because Heaven represents what Earth is supposed to be like. Heaven, the Christian’s final destination, is a perfected and transformed Earth. Heaven is what Earth was supposed to be before sin entered the world and corrupted it.

It is only by focusing on what is supposed to be, that we will change what is. C. S. Lewis says this eloquently in Mere Christianity:

If you read history, you will find that the Christians who did most for the present world were just those who thought most of the next. The Apostles themselves, who set on foot the conversion of the Roman Empire, the great men who built up the Middle Ages, the English Evangelicals who abolished the Slave Trade, all left their mark on Earth, precisely because their minds were occupied with Heaven. It is since Christians have largely ceased to think of the other world that they have become so ineffective in this. Aim at Heaven and you will get earth ‘thrown in’: aim at earth and you will get neither.

Randy Alcorn summarizes the point: “We need a generation of heavenly minded people who see human beings and the earth itself not simply as they are, but as God intends them to be.” So, rather than chide Christians for focusing on Heaven too much, the non-Christian should hope that Christians do just the opposite!

The Christian vision of Heaven is what drives us to improve the Earth we currently call “home.”
