It is a holy thing to heal the sick and the sinning through prayer as Christ Jesus did. And there are men, women, and children in many parts of the world who are doing this through their understanding of Christian Science. They have also maintained health, many of them all their lives, without having taken medicine, without having had a physical examination or a diagnosis. To many unacquainted with Christian Science, it may seem unwise not to have at least one physical checkup during the year, just to be on the safe side. But those who understand the truth of being in Christian Science know that by not yielding their thoughts and bodies to the world's customary search for cause and life in matter and by relying entirely upon God for the prevention and healing of disease, they are on the safest side of all.
In his first Epistle to the Corinthians, Paul wrote, "We speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual" (2:13). The practice of Christian Science compares "spiritual things with spiritual." It recognizes the real man to be the effect of the one perfect cause, Spirit, or God, and shows him to be the perfect expression of the Mind that is God, good. The truth of this statement, realized and applied, restores harmony to discordant human conditions of every nature.
In the Biblical accounts of the healing works of Christ Jesus, there is no record of his ever having examined his patients physically, and seldom did he ask questions regarding their ailments. He compared "spiritual things with spiritual" by knowing that man is spiritual, individually perfect, and that he remains so eternally, unaffected by the world's belief in heredity or any other supposed law of mortal mind.
