Brother, happy Sabbath, which starts this Friday October 28, 2022 at 10:53 am EDT! Jesus used Paul in the book of Hebrews to correct the ancient human tradition that the Sabbath travels with the week when God showed in the desert since Joshua that it is kept around the world in the time zone of creation in Eden, a mistake humans have not listened to correct for more than 3,000 years. The struggle of "mind" over "flesh" is not between two natures. Paul tells us who we really are, our "mind" is who we are in the present, and our "flesh" shows who we were until it catches up to the "mind".
I want to do what is good, but I don’t. I don’t want to do what is wrong, but I do it anyway. But if I do what I don’t want to do, I am not really the one doing wrong; it is sin living in me that does it. (Romans 7:19-20 NLT)
Jesus allows you through practice to change the "flesh" with your "mind", which, with practice, will guide your "flesh" to conform to your "mind". It is like the desire to learn to play the piano, it takes a lot of practice to get the body to do what we want. An analogy to the captain of the Titanic should help shed light on the struggle. The "mind" is the captain of the "flesh" telling the "flesh" to deviate from its current course toward destruction, but the "flesh" turns very slowly, like when the Titanic couldn't help but collide with an iceberg, but the grace of Jesus is like having all the time you need to turn away from the iceberg that sank the Titanic.
And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice—the kind he will find acceptable. This is truly the way to worship him. Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think. Then you will learn to know God’s will for you, which is good and pleasing and perfect. (Romans 12:1-2 NLT)
It is the "mind" that guides the "flesh" to become, as Paul tells us, "slaves to righteous living", Jesus having freed us from our former "slavery to sin" by allowing our "flesh" to change through practice guided by our "mind". Jesus' cycle of forgiving our past sins is the remedy Paul gives to the struggle of our "mind" over our "flesh" by allowing growth through practice which the law does not permit without the daily forgiveness of our High Priest Jesus.
Wretched man that I am! who shall deliver me out of the body of this death? I thank God through Jesus Christ our Lord. So then I of myself with the mind, indeed, serve the law of God; but with the flesh the law of sin. (Romans 7:24-25 NLT)
United in our hope for the soon return of Jesus, Jorge
