A child may say she will be "grown up" when she can dress herself. A teen-ager often equates adulthood with owning his or her own car. Adults sometimes measure their maturity by position attained, possessions acquired, or a life style compatible with preconceived material standards.
Christ Jesus, more than anyone else who has ever lived, knew we all need the spiritual maturity that enables us to be what we are—the children of God. Conventional goals did not appear to concern him. His love of God made him constantly appreciative of God's allness and ready to demonstrate a heritage of spiritual good as proof of it.
At a point early in his ministry, Jesus was tempted to give power to matter and to suppose that power could be personally claimed. But he refused to submit to anything that would deny spiritual good as the only substance. He rejected everything that would deny God as the only power or operating force in the universe. He made it his lifework to express the one, infinite divine Life. He lived the qualities related to Love, Truth, Mind, Principle. His is the perfect example of spiritual maturity.
