Purpose is one of the most important values in human life. It is the value that answers the question “What for?”—the value that motivates us to think, strive, and thrive—the value by reference to which we focus our minds, direct our actions, and pursue our goals.

And it is under assault by advocates of religion.

Religionists bastardize the concept of “purpose” (and the related concept of “meaning”) in an effort to convince people—often the young—that there can be no objective purpose in life unless it comes ultimately from God.

To wit:

“If there is no God,” writes theologian William Lane Craig, “there is no purpose” and “there can be no objective meaning in life.”1

Pastor Rick Warren writes, “Without God, life has no purpose, and without purpose, life has no meaning.”2

Dennis Prager claims, “If there is no God who designed the universe and who cares about His creations, life is ultimately purposeless,” and “there is no objective meaning to life.”3

Ben Shapiro elaborates, “God expects things of us . . . He has standards for our behavior . . . He demands our holiness”—and “His standards of truth matter, not our own.” Thus, having a “moral purpose” consists in “living the life God wants for [us]”—the life God laid out for us “through a series of rules to be found in His holy book.” And, Shapiro emphasizes, according to the Bible, living this way is not morally optional; it is morally mandatory: “As King Solomon concludes in Ecclesiastes, the purpose of human existence is simple: “Fear God and keep his commandments, for this is the whole duty of man.”4

Why is this our duty? Why must we obey God’s commandments and live the life he wants for us? . . .

Your parents made you, and you have no moral obligation to live the life they want for you. You are a sovereign being with a mind and free will, and you can think and choose for yourself. And, according to rational morality, if you choose to live, you have a moral responsibility to think and choose for yourself.

19. Deuteronomy 22:28–29, Numbers 31:15–18. Lest anyone claim that such commandments are found only in the Old Testament, bear in mind that the Old Testament is as much a part of Christianity as is the New Testament. According to Christianity, there is one God, and all of his laws, including those spelled out in the Old Testament, must be upheld. The New Testament is crystal clear about this. In the words of Jesus: “It is easier for heaven and earth to pass away than for one dot of the [Old Testament] Law to become void” (Luke 16:17). And: “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven” (Matthew 5:17–19).

20. Al-Baqarah 2:191, At-Tawbah 9:5.

21. An-Nisa 4:24, Al-Ahzab 33:50.

22. E.g., see Rabbi Jonathan Sacks, “What is the Purpose of Life?,” TorahCafe,; and William Lane Craig, “What Is The Purpose and Meaning of Life Without God?,” Regarding the latter, William Lane Craig’s claim that if the universe has no purpose, then you can’t have an ultimate purpose is ridiculous. It’s like standing on a rock and saying, “If this rock has no purpose, then I can’t have an ultimate purpose.” Likewise, his claim to the effect that if life is not eternal—if it ends—then it is meaningless, makes no sense. That’s like saying, “If this article ends, then it’s meaningless.”
