The Bible offers shining examples of enduring vitality and strength expressing the immortality of our Maker, divine Spirit. They demonstrate the fallacy of the supposed inevitability of aging, deterioration, or any lessening of God-given talents and abilities. Caleb, said to have “wholly followed the Lord,” declared at eighty-five that he was as vital and fit as he’d been 45 years earlier when Moses sent him to “espy out the land” of Canaan (see Joshua 14:6–11). Moses’ own demanding mission leading the children of Israel to the Promised Land—a journey that ended with them wandering through the wilderness for forty years—didn’t begin until he was eighty. And several women in the Bible—for instance, Sarah, Hannah, and Elizabeth—gave birth when well beyond typical childbearing years. 

Is it equally possible today to be free of effects commonly associated with aging? It is, through the acknowledgment of the spiritual fitness, vitality, and vigor of God’s immortal creation—His wholly spiritual image and likeness (see Genesis 1:26, 27).

This is the radical, key concept that distinguishes the demonstrable theology of Christian Science from any other system of thought: Perfect God, divine and immortal Spirit, made man—all of us—perfect and immortal in His image and likeness; therefore, man is entirely spiritual, not material or a mixture of matter and Spirit. Knowing this frees us from limitations and unfolds the divine possibilities of demonstrating Life as God, good.
