And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. I should lose nothing - It is the will of God that every soul who believes should continue in the faith, and have a resurrection unto life eternal. But he wills this continuance in salvation, without purposing to force the persons so to continue. God may will a thing to be, without willing that it shall be. Judas was given to Christ by the Father, John 17:12. The Father willed that this Judas should continue in the faith, and have a resurrection unto life eternal: but Judas sinned and perished. Now it is evident that God willed that Judas might be saved, without willing that he must be saved infallibly and unconditionally. When a man is a worker together with the grace of God, he is saved; when he receives that grace of God in vain, he is lost - not through a lack of will or mercy in God, but through lack of his co-operation with Divine grace. God saves no man as a stock or a stone, but as a reasonable being and free agent. "That which thou hast heard, thou mayest hold fast, and persevere in, if thou wilt," Says St. Augustin. In eo quod audieras, et tenueras, perseverares, si velles. De Correct. & Grat. c. 7. See Calmet.
Raise it up again at the last day - The Jews believed that the wicked should have no resurrection; and that the principle that led to the resurrection of the body, in the righteous, was the indwelling Spirit of God. This is positively asserted in the Shir Hashirim Rabba. See Schoettgen.
