The time Christians give to prayer and communion with God is not meant for their natural lives but meant to nourish the life of the Son of God in them.  God engineers the circumstances of His saints in order that the spirit may use them as the praying-house of the Son of God.

When I am born from above, the life of the Son of God is born in me, and I have to take time to nourish my life. 

The essential meaning of prayer is that it nourishes the life of the Son of God in me and enables Him to manifest Himself in my mortal flesh.

- Oswald Chambers, in "Biblical Ethics"

“By prayer and faith, we may obtain all necessary temporal and spiritual help and blessings. In all simplicity, we can pour out our heart before God. Then we have to believe that He will give to us according to our need."

- G. Muller, in “The Autobiography of George Muller”

“When we pray, we speak to God.  This exercise of the soul can be best performed after the inner man has been nourished by meditation on the Word of God.”

“As my heart is nourished by the truth of the Word, I am brought into true fellowship with God.  I speak to my Father and to my Friend (although I am unworthy) about the things that He has brought before me in His precious Word.”

“Through His Word, our Father speaks to us, encourages us, comforts us, instructs us, humbles us, and reproves us.”

- G. Muller, in “The Autobiography of George Muller”

“Neither eloquence nor depth of thought makes a truly great preacher. Only a life of prayer and meditation will render him a vessel ready for the Master’s use and fit to be employed in the conversion of sinners and in the edification of the saints.”

- G. Muller, in “The Autobiography of George Muller”

“I seldom use any other study aids besides the Scriptures and some good translations in other languages. My chief help is prayer.  Whenever I study a single part of divine truth, I always gain some light about it after praying and meditating over it.”

- G. Muller, in “The Autobiography of George Muller”

"True prayer is prayer in the Spirit (i.e., the prayer that the Holy Spirit inspires and directs".

"True thanksgiving is 'unto God and the Father,' through or 'in the name of our Lord Jesus Christ,' in the Holy Spirit."

"There is no true and acceptable worship except that which the Holy Spirit prompts and directs."

--- R. A. Torrey, in "The Person and Work of the Holy Spirit"

"Avoid every tendency away from the simplicity of relationship to God in Christ Jesus, and then prayer will be as the breath of the lungs in a healthy body."

--- Oswald Chambers, "Christian Disciplines" ---

"Jesus Christ carries on intercession for us in heaven, the Holy Spirit carries on intercession in us on earth; and we the saints have to carry on intercession for all men."

--- Oswald Chambers, "Discipline of Prayer" ---
