"There is need of prayer,—most earnest, fervent, agonizing prayer,—such prayer as David offered when he exclaimed: “As the hart panteth after the water brooks, so panteth my soul after Thee, O God.” “I have longed after Thy precepts;” “I have longed for Thy salvation.” “My soul longeth, yea, even fainteth for the courts of the Lord: my heart and my flesh crieth out for the living God.” “My soul breaketh for the longing that it hath unto Thy judgments.” This is the spirit of wrestling prayer, such as was possessed by the royal psalmist. 4T 534.2"
"As the hart panteth after the water brooks, so panteth my soul after thee, O God."
EGW directly quotes Psalm 42:1.
"My soul breaketh for the longing that it hath unto thy judgments at all times."
EGW directly quotes Psalm 119:20.
"My soul longeth, yea, even fainteth for the courts of the Lord: my heart and my flesh crieth out for the living God."
EGW directly quotes Psalm 84:2.
"Daniel prayed to God, not exalting himself or claiming any goodness: “O Lord, hear; O Lord, forgive; O Lord, hearken and do; defer not, for Thine own sake, O my God.” This is what James calls the effectual, fervent prayer. Of Christ it is said: “And being in an agony He prayed more earnestly.” In what contrast to this intercession by the Majesty of heaven are the feeble, heartless prayers that are offered to God. Many are content with lip service, and but few have a sincere, earnest, affectionate longing after God. 4T 534.3"
"Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much."
EGW directly quotes James 5:16.
"And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground."
EGW directly quotes Luke 22:44.
"And I prayed unto the Lord my God, and made my confession, and said, O Lord, the great and dreadful God, keeping the covenant and mercy to them that love him, and to them that keep his commandments;"
EGW directly quotes Daniel's prayer, although not verse 4 specifically, the context is Daniel's prayer.
"Communion with God imparts to the soul an intimate knowledge of His will. But many who profess the faith know not what true conversion is. They have no experience in communion with the Father through Jesus Christ, and have never felt the power of divine grace to sanctify the heart. Praying and sinning, sinning and praying, their lives are full of malice, deceit, envy, jealousy, and self-love. The prayers of this class are an abomination to God. True prayer engages the energies of the soul and affects the life. He who thus pours out his wants before God feels the emptiness of everything else under heaven. “All my desire is before Thee,” said David, “and my groaning is not hid from Thee.” “My soul thirsteth for God, for the living God: when shall I come and appear before God?” “When I remember these things, I pour out my soul in me.” 4T 534.4"
"The sacrifice of the wicked is an abomination to the Lord: but the prayer of the upright is his delight."
Both passages contrast the prayers of the wicked with the prayers of the righteous, and state that the former are an abomination to God.
"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven."
Both passages discuss the importance of not just saying you are a believer, but actually living a life that reflects that belief.
