There is a very beautiful passage in the Hebrew sacred poetry expressive of the relation of the Divine life to the cure of all mental and bodily maladies: “Bless the Lord, O my soul, and forget not all His benefits: who forgiveth all thine iniquities; who healeth all thy diseases; who crowneth thee with loving kindness and tender mercies, who satisfieth thy mouth with good things; so that thy youth is renewed as the eagles.” (Psalm 103:2-5.)

So fully convinced was the great religious poet of the Hebrews that the Lord was the source and the “strength of our life” (Psalm 27:1) that he believed He (God) could save us from the most fatal epidemics,–from the pestilence that walketh in darkness, and from the destruction that wasteth at noonday. (Psalm 91:6) … So when a man attains to the consciousness of the immanence of God in his individual being, and that his “life is hid with Christ in God” (Colossians 3:3), he is an incarnation of the Deity, a divine theophany, a manifestation
of God in the flesh. He is a partaker of the divine nature (2 Peter 1:4), and thus is strengthened with might in the inner man (Ephesians 3:16)

The whole life of Jesus the Christ was the highest exemplification of the power of this idea ever witnessed in the history of the race, and a demonstration of its theoretical and practical truth. He cured diseases of mind and body by bringing men into conscious contact with the one and only Life. Thus we see that the higher forms of the religious life, and the state of mind and body which we designate by the name of health, are closely associated. The radical significance of the word religion is that of reunion, or a binding together of what has been sundered. When realized in its full import, it unites the body to the soul in a living correspondence, and consciously connects the soul with God in an influential sympathetic union. In this state of conjunction with the Lord of life, and the Father of spirits, the boundary line between our individual existence and the Divine Being becomes more dimly defined and each soul becomes in a degree a repetition of the Christ in another personality, and the answer of the prayer of Jesus is fulfilled, that we might become one with God as he and the Father were one. (John 17:21-23.) In this state we lay hold of eternal life; death is annihilated, and disease loses its reality. Our life is so linked with the Divine Being that because He lives we live also.

No one has life in himself, self-originated and underived, but it is the perpetual gift of God. It is also intuitively certain that the same is true of health. Vital force in its last analysis is the life of God in man, and every man can say, in the language of David, that the Lord is the “health of his countenance.” (Psalm 42:11 ; Psalm 43:5.)
