Mark the progress of the thought. What was mercy to Abraham was truth to Jacob. God was under no obligation to extend covenant blessings; hence it was to Abraham a simple act of pure mercy; but, having so put Himself under voluntary bonds, Jacob could claim as truth what to Abraham had been mercy. So in 1 John i. 9:
"If we confess our sins He is faithful and just to forgive us our sins, And to cleanse us from all unrighteousness."
Plainly, forgiveness and cleansing are not originally matters of faithfulness and justice, but of mercy and grace. But, after God had pledged Himself thus to forgive and cleanse the penitent sinner who confesses and forsakes his sins,* what was originally grace and mercy becomes faithfulness and justice; for God owes it to Himself and to His creature to stand by His own pledge, and fulfil the lawful expectation which His own gracious assurance has created.
* Proverbs xxviii. 13.
Thus we have not only examples of argument in prayer, but concessions of the living God Himself, that when we have His word to plead we may claim the fulfillment of His promise, on the ground not of His mercy only, but of His truth, faithfulness, and justice. Hence the 'holy boldness with which we are bidden to present our plea at the throne of grace. God owes to His faithfulness to do what He has promised, and to His justice not to exact from the sinner a penalty already borne in his behalf by His own Son.
No man of his generation, perhaps, has been more wont to plead thus with God, after the manner of holy argument, than he whose memoir we are now writing. He was one of the elect few to whom it has been given to revive and restore this lost art of pleading with God. And if all disciples could learn the blessed lesson, what a period of renaissance of faith would come to the church of God!
George Müller stored up reasons for God's intervention, As he came upon promises, authorized declarations of God concerning Himself, names and titles He had chosen to express and reveal His true nature and will, injunctions and invitations which gave to the believer a right to pray and boldness in supplication—as he saw all these, fortified and exemplified by the instances of prevailing prayer, he laid these arguments up in memory, and then on occasions of great need brought them out and spread them before a prayer-hearing God. It is pathetically beautiful to follow this humble man of God into the secret place, and there hear him pouring out his soul in these argumentative pleadings, as though he would so order his cause before God as to convince Him that He must interpose to save His own name and word from dishonour!
These were His orphans, for had He not declared Himself the Father of the fatherless? This was His work, for had He not called His servant to do His bidding, and what was that servant but an instrument that could neither fit itself nor use itself? Can the rod lift itself, or the saw move itself, or the hammer deal its own blow, or the sword make its own thrust? And if this were God's work, was He not bound to care for His own work? And was not all this deliberately planned and carried on for His own glory? And would He suffer His own glory to be dimmed? Had not His own word been given and confirmed by His oath, and could God allow His promise, thus sworn to, to be dishonoured even in the least particular? Were not the half-believing church and the unbelieving world looking on, to see how the Living God would stand by His own unchanging assurance, and would He supply an argument for the skeptic and the scoffer? Would He not, must He not, rather put new proofs of His faithfulness in the mouth of His saints, and furnish increasing arguments wherewith to silence the cavilling tongue and put to shame the hesitating disciple?*
* Mr. Müller himself tells how he argued his case before the Lord at this time. (Appendix F. Narrative, vol. 1, 243, 244)
In some such fashion as this did this lowly-minded saint in Bristol plead with God for more than threescore years, and prevail—as every true believer may who with a like boldness comes to the throne of grace to obtain mercy and find grace to help in every time of need. How few of us can sincerely sing:
