Then Jesus said to his disciples, “If anyone wants to become my follower, he must deny himself, take up his cross, and follow me. For whoever wants to save his life will lose it, but whoever loses his life because of me will find it.”
*Also parallel passages in Mark 8:34-35 & Luke 9:23-24
I have been crucified with Christ, and it is no longer I who live, but Christ lives in me. So the life I now live in the body, I live because of the faithfulness of the Son of God, who loved me and gave himself for me.
Now those who belong to Christ have crucified the flesh with its passions and desires.
because the outlook of the flesh is hostile to God, for it does not submit to the law of God, nor is it able to do so. Those who are in the flesh cannot please God. You, however, are not in the flesh but in the Spirit, if indeed the Spirit of God lives in you.
For the grace of God has appeared, bringing salvation to all people. It trains us to reject godless ways and worldly desires and to live self-controlled, upright, and godly lives in the present age,
1 Peter 4:1-2
So, since Christ suffered in the flesh, you also arm yourselves with the same attitude, because the one who has suffered in the flesh has finished with sin, in that he spends the rest of his time on earth concerned about the will of God and not human desires.
