22. Observe, the apostle alludes to his prayer by naming its outward expression—bending the knees. But the external posture, if accompanied by nothing else, is sheer hypocrisy. When prayer is genuine, possessing the fire by which it is kindled, prompted by a sincere heart which recognizes its need and likewise the blessings that are ours as proclaimed in the Word, and when faith in God's Word—in his promise—revives, then the individual will be possessed with a fervor prompting him to fall upon his knees and pray for strength and for the power of the Spirit. When the Spirit of prayer is enkindled and burns within the heart, the body will responsively assume the proper attitude; involuntarily, eyes and hands will be upraised and knees bended. Witness the examples of Moses, David and even Christ himself.
When we pray with glowing hearts, external gestures will take care of themselves. They are prompted by the Spirit, and therefore are not to be denounced. If assumed, unbidden of the Spirit, they are hypocritical; as, for instance, when one presumes outwardly to serve God and perform good works while his heart is far away. The prophet says (Is 29, 13), "This people draw nigh unto me, and with their mouth and with their lips do honor me, but have removed their heart far from me."
23. By the declaration, "I bow my knees unto the Father of our Lord Jesus Christ," Paul establishes the doctrine that no one should presume to speak to God, to entreat him for any favor, unless approaching, as Paul does here, in the name of "the Father of our Lord Jesus Christ." For Christ is our sole Mediator, and no one need expect to be heard unless he approach the Father in the name of that Mediator and confess him Lord given of God as intercessor for us and ruler of our bodies and souls. Prayer according to these conditions is approved. Strong faith, however, is necessary to lay hold of the comforting Word, picturing God in our hearts as the Father of our Lord Jesus Christ.
24. The statement that Christ is our Lord is very comforting, though we have made it terrifying by regarding Christ as a stern and angry judge. But the fact is, he is Lord for the sole purpose of securing us against harsh lords, tyrants, the devil, the world, death, sin and every sort of misfortune. We are his inheritance, and therefore he will espouse our cause, deliver us from violence and oppression of all kinds and better our condition.
The name "Lord," then, is altogether lovable and comforting to us who believe, and gives us confidence of heart. But still more comforting is it to know that our God, our Lord, is the Father of our Lord Jesus Christ. The name "Lord" stands for the complete Godhead, who gives himself to us. Therefore, all we ask in this name must be abundantly bestowed. Naught is here for me but real help and pure grace. For God designs to have me his child in Christ, placed above all things temporal and eternal.
