Faith finds its appropriate and natural expression in prayer, which, in the system of cure adopted and practised by Christ, and by his primitive followers, occupies a prominent place, and demands consideration. … In the prayer of faith and love it is …a spiritual necessity. The soul is drawn to the mercy-seat from an irresistible divine attraction.

It is a spontaneous breathing of the soul, and as natural as the respiration of the body. It is the communion of the living soul with a living and present God. Such was the prayer of Christ, who … spent whole nights in communion with the All-Father in nature’s sublimest temple, the solitude of mountains. On one occasion it is said that as he prayed, “The fashion of his countenance was altered, and his raiment was white and glistering.” (Luke 9:29)

It is a truth of the intuitive reason, that God is the Infinite Life, and such intimate fellowship with the primal and only source of our being must have its influence upon the health of the soul, and through this upon the body.

Communion with God is rendered possible by the laws governing the (communication) of spirit with spirit, of mind with mind. It brings the soul in spiritual contact with the only fountain of life. All creeds and liturgies and priestly intercessors are removed, and the soul, “by a new and living way,” comes into the holy of holies, and has fellowship with God. … In every human soul, overlaid as it may be by a deep covering of externality, there is a divine realm that constitutes a point of contact between itself and God. It is here that the divine and and human meet and mingle, and God has his habitation.

In the Christian system prayer is made a prominent instrumentality in the cure of disease. Its plain assertion and promise are, “The prayer of faith shall save the sick, and the Lord shall raise him up.” (James 5:15). …The most intense and influential action of one mind upon another is that which goes forth in prayer for another … There is a prayer that cannot be “worded,” as the original term employed by Paul signifies. (Romans 8:26) Prayer becomes oftentimes more efficacious in proportion as it become internal. … “ The deepest prayer of all is not only without utterance, not only without words, but even goes down below the region of distinct thought. It is simply turning to God and opening the heart to him, to receive whatever influence he may send” (Christian Doctrine of Prayer, Dr. James Freeman Clarke). … When such a spirit of prayer enters into words, they are “heart deep,” and radiant with love and spiritual life.

There are deep places of the soul of man that are near the region where Divinity is incarnated in humanity.

What God has spoken he speaks now. … (His promises) do not belong to the dead past, but to the living present. The existence of God is a nunc stans, an eternal now.

Warren Felt Evans, Soul and Body;
or The Spiritual Science of Health and Disease, 1876.

Likewise the Spirit also helps in our weaknesses.
For we do not know what we should pray for as we ought,
but the Spirit Himself makes intercession for us
with groanings which cannot be uttered.

Romans 8:26
