George Mueller emphasizes the power of prayer in supporting the orphan work, presenting various arguments to God for His provision. He highlights that the work is for God's glory, that God is the Father of the fatherless, and that the children have been received in Jesus' name. Mueller expresses concern for the faith of believers, the potential mockery from enemies, and the burden he carries for the orphans. He pleads for God's continued support to demonstrate His faithfulness and to counter doubts about the sustainability of the work. Ultimately, he seeks assurance that God's past answers to prayer will not be in vain.

THE arguments which I plead with God are: ​1. That I set about the work for the glory of God, i.e., that there might be a visible proof, by God supplying, in answer to prayer only, the necessities of the orphans, that He is the living God, and most willing, even in our day, to answer prayer: and that, therefore, He would be pleased to send supplies. 2. That God is the "Father of the fatherless," and that He, therefore, as their Father, would be pleased to provide. (Psalm lxviii.5.) 3. That I have received the children in the name of Jesus, and that, therefore, He, in these children, has been received, and is fed, and is clothed; and that, therefore, He would be pleased to consider this. (Mark ix.36,37.) 4. That the faith of many of the children of God has been strengthened by this work hitherto, and that, if God were to withhold the means for the future, those who are weak in faith would be staggered; whilst, by a continuance of means, their faith might still further be strengthened. 5. That many enemies would laugh, were the Lord to withhold supplies, and say, "Did we not foretell that this enthusiasm would come to nothing?" 6. That many of the children of God, who are uninstructed, or in a carnal state, would feel themselves justified to continue their alliance with the world in the work of God, and to go on as heretofore, in their unscriptural proceedings respecting similar instituions, so far as the obtaining of means is concerned, if He were not to help me. 7. That the Lord would remember that I am His child and that He would graciously pity me, and remember that I cannot provide for these children, and that therefore He would not allow this burden to lie upon me long without sending help. 8. That He would remember likewise my fellow labourers in the work, who trust in Him, but who would be tried were He to withhold supplies. 9. That He would remember that I should have to dismiss the children from under our Scriptural Institution to their former companions. 10. That He would show that those were mistaken who said that, at the first, supplies might be expected while the thing was new, but not afterwards. 11. That I should not know, were He to withhold means, what construction I should put upon all the many most remarkable answers to prayer which He has given me heretofore in connection with this work, and who most fully have shown to me that it is of God.
