Paul uses this question to express great emotion. If your language has a way of showing great emotion through an exclamation or a question, use it here. AT: "I want someone to set me free from the control of what my body desires!" (See: [[rc://en/ta/man/translate/figs-rquestion]])
The mind and flesh are used here to show how they compare to serve either God's law or the principle of sin. With the mind or intellect one can choose to please and obey God and with the flesh or physical nature to serve sin. AT: "My mind chooses to please God, but my flesh chooses to obey sin" (See: [[rc://en/ta/man/translate/figs-metaphor]])
