A note from Owen

From the Mortification of Sin in Believers:

Of Romans 8.12-13: So then, brothers, we are debtors, not to the flesh, to live according to the flesh. For if you live according to the flesh you will die, but if by the Spirit you put to death the deeds of the body, you will live.

John Owen ~
"The certainty of the coherence and connection that is between the things spoken of; as we say to a sick man, 'If you will take such a potion, or use such a remedy, you will be well.' The thing we solely intend to express is the certainty of the connection that is between the potion or remedy and health. And this is the use of it here. The certain connection that is between the mortifying of the deeds of the body and living is intimated in this conditional particle."

Reminds me of the words of our Savior:

Matthew 18.9: And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter life with one eye than with two eyes to be thrown into the hell of fire.
