Romans 8:27

"But He that searcheth the hearts." You see that it is not about the Comforter that he is speaking, but about the spiritual heart. Since if this were not so, he ought to have said, "He that searcheth" the Spirit. But that thou mayest learn that the language is meant of a spiritual man, who has the gift of prayer, he proceeds, "And he that searcheth the hearts knoweth what is the mind of the Spirit," that is, of the spiritual man. "Because he maketh intercession for the saints according to the will of God." Not (he means) that he informs God as if ignorant, but this is done that we may learn to pray for proper things, and to ask of God what is pleasing to Him. For this is what the "according to God" is. And so this was with a view to solace those that came to Him, and to yield them excellent instruction. For He that furnished the gifts, and gave besides blessings without number, was the Comforter. Hence it says, "all these things worketh one and the self-same Spirit." And it is for our instruction that this takes place, and to show the love of the Spirit, it condescendeth even to this. And it is from this that the person praying getteth heard, because the prayer is made "according to the will of God." You see from how many points he instructs them in the love that was shown them and the honor that was done them. And what is there that God hath not done for us? The world He hath made corruptible for us, and again for us incorruptible. He suffered His Prophets to be ill-treated for our sake, sent them into captivity for us, let them fall into the furnace, and undergo ills without number. Nay, He made them prophets for us, and the Apostles also He made for us. He gave up for us His Only-Begotten, He punisheth the devil for us, He hath seated us on the Right Hand, He was reproached for us. "For the reproaches of them that reproached thee," it says, "fell upon me."
