"He who has the spirit of prayer has the highest interest in the court of heaven. And the only way to retain it is to keep it in constant employment. Apostasy begins in the closet. No man ever backslid from the life and power of Christianity who continued constant and fervent in private prayer. He who prays without ceasing is likely to rejoice evermore."
— Adam Clarke
Messages on Prayer
PRAYER has to do with the entire man. Prayer takes in man in his whole being, mind, soul and body. It takes the whole man to pray, and prayer affects the entire man in its gracious results. As the whole nature of man enters into prayer, so also all that belongs to man is the beneficiary of prayer. All of man receives benefits in prayer. The whole man must be given to God in praying. The largest results in praying come to him who gives himself, all of himself, all that belongs to himself, to God. This is the secret of full consecration, and this is a condition of successful praying, and the sort of praying which brings the largest fruits.

"Satan dreads nothing but prayer... The Church that lost its Christ was full of good works. Activities are multiplied that meditation may be ousted, and organizations are increased that prayer may have no chance. Souls may be lost in good works, as surely as in evil ways. The one concern of the devil is to keep the saints from praying. He fears nothing from prayerless studies, prayerless work, prayerless religion. He laughs at our toil, mocks at our wisdom, but trembles when we pray."
— Samuel Chadwick
"The neglect of prayer is a grand hindrance to holiness. "We have not because we ask not." Oh, how meek and gentle, how lowly in heart, how full of love both to God and to man, might you have been at this day, if you had only asked! If you had continued instant in prayer! Ask, that you may thoroughly experience and perfectly practice the whole of that religion which our Lord has so beautifully described in the Sermon on the Mount."
— John Wesley
"A proper idea of prayer is the pouring out of the soul before God, with the hand of faith placed on the head of the Sacrificial Offering, imploring mercy, and presenting itself a free-will offering of itself unto God, giving up body, soul and spirit, to be guided and governed as may seem good to His heavenly wisdom, desiring only perfectly to love Him, and to serve Him with all its powers, at all times, while He has a being."
— Adam Clarke
"Every promise of Scripture is a writing of God, which may be pleaded before Him with this reasonable request: "Do as Thou hast said." The Creator will not cheat His creature who depends upon His truth; and, far more, the Heavenly Father will not break His word to His own child. "Remember the word unto Thy servant, on which Thou hast caused me to hope," is most prevalent pleading. It is a double argument: It is Thy Word, wilt Thou not keep it? Why hast Thou spoken of it if Thou wilt not make it good? Thou hast caused me to hope in it; wilt Thou disappoint the hope which Thou hast Thyself begotten in me?"
— Charles H. Spurgeon
