Theodoret of Cyrus, on Rom 8:27

“And he that searcheth the hearts, knoweth what the Spirit desireth; because he asketh for the saints according to God.”

“"Spirit" here does not mean the substance of the Spirit but rather the grace which is given to believers. By this grace we are encouraged to struggle, we are inflamed to pray more earnestly, and with ineffable sighings we implore God the Savior. The holy apostle wrote this out of the experience of his own suffering. For he himself had asked to be set free from evils, not once or twice but three times, but he did not get what he asked for. Rather, he heard God say: "My grace is sufficient for you, for my power is made perfect in weakness." But when he learned this, he willingly embraced the things which he had asked to be set free from and said: "I will all the more gladly boast of my weaknesses, that the power of Christ may rest upon me."”
