"But even this is not clear. What, then, does he say? A fleshly man, he says, that is, one attached only to the present, always living in the present, and not under the influence of the Spirit of God, can go everywhere and wander where he likes."
"By contrast, one who is subject to the Spirit of God, and is led and governed by Him, cannot always be master of his own will, since he depends on the authority of the Spirit."
"The same thing happens to him as to a faithful servant, who knows only how to carry out his master's commands. He has no authority over himself and does not know rest even for a little while."
"Sometimes he promises something to his companions, but later does not fulfill his promise when it proves contrary to the will of his master. This is what the Apostle's words mean: I do not plan according to the flesh."
"That is, I am under the governance of the Spirit of God and do not have authority to go where I wish. I am subject to the authority and commands of the Spirit of God, and His voice governs and guides me."
"Therefore I could not come to you, for this was not pleasing to the Spirit of God." Similar things are often said in the Acts of the Apostles (Acts 16:6-9).
The Apostles intended to go to one place, but the Spirit of God commanded them to go to another entirely.
"Thus the fact that I did not come to you, despite my promise, did not depend on my frivolity or inconstancy, but on the Spirit of God, to Whom I am subject and Whom I must obey."
"What then? someone may say. Did the Apostle not promise to come by the inspiration of the Spirit of God? No, not by the inspiration of the Spirit. This promise was the work of his love for the Corinthians."
Saint Chrysostom's thought is this: whoever plans according to the flesh, once he decides to do something, strives to do it at any cost in order to stand on his own decision.
He wants his yes to be yes, and his no to be no. Blessed Theodoret expresses the Apostle's thought in this way: "I am not enslaved to passion, he says, so that, one way or another, I must fulfill my desire."
"Whoever follows the desires of the flesh is carried away by his own thoughts, even if they are utterly absurd. But whoever forms a sober intention, even if the thing intended is good, does not carry out his purpose if he notices that it brings no benefit to others."
"And that, as soon as we see something useful for you, we offer it to you zealously and without the least hesitation is witnessed by the preaching. For although we offered it to you repeatedly, we did not change our words."
The last words of blessed Theodoret serve as a transition to the Apostle's next words.
