"Are you in fact wanting what's possible and in particular what's possible for you? If so, why are you obstructed? Why are you discontented? Are you in fact avoiding what's unavoidable? If so, why do you encounter difficulties of any kind? Why do you meet with misfortune? Why do things that you want to happen not happen, while things you don't want to happen do happen? That's unmistakable evidence of a discontented and unhappy existence. 'I want something and it doesn't happen; am I not the most wretched creature in the world? I don't want something and it does happen: am I not the most wretched creature in the world?' ... 'in short, align what you want with what God wants. Who will impede you then? Who will constrain you? No one, any more than they could impede or constrain Zeus. When you have Zeus as your commander and align your wishes and desires with his, can you still be afraid of failing to get what you want? Give your desire and aversion over to poverty and wealth, and you'll fail to get what you desire and meet with what you want to avoid. Give them over to health, and you'll be miserable. Give them over to political power, honors, country, friends, children--in short, to anything that isn't subject to will--and the same goes. But give them over to Zeus and the gods--hand them over to them, put them in their charge, enroll them in their command--and how could you still be discontented?"

"Because I don't know what I'm achieving; because I'm not practicing what I want, but I'm doing this thing I hate. And if I don't want this thing I'm doing, I'm in agreement with the rule that it's good. But now I am no longer achieving it but the error residing within me. Because I know that within me doesn't reside, that is, within my flesh, good; because the willing is there in me, but the achieving the good is not; because I'm not doing the good I want, but I'm practicing this bad thing I don't want. And if I'm doing this thing I don't want, I'm no longer achieving it but the malfunction residing within me. I'm then finding the rule, for me who is willing to do the good, that the bad is there in me; because I am rejoicing together with the rule of the God in line with the internal person, yet I'm looking at a different rule among my body parts soldiering against the rule of my intellect and capturing me with the rule of the malfunction which exists within my body parts. I am a miserable human being; who will rescue me from this body of death? But charity to the God through Yeshua the Anointed our Lord. Therefore then I myself am in fact enslaved by the intellect to the divine rule, yet by the flesh to the rule of the malfunction. Nothing therefore is now a condemnation against those within the Anointed Yeshua not walking in line with the flesh, but in line with the Pneuma."
Romans 7:15-8:1
