[Salvation]

Another bit of wisdom:

The flesh is intent on things of this world, upon gratifying its own passions and desires. On account of the flesh we are concerned primarily with ourselves and seek to be at the center.

[Salvation]

That is ultimately what God can and will do for us. He will put the flesh to death in us and bring alive our spirit by the power of his Holy Spirit.
But step one is to appreciate what the flesh is and understand its moves.
Step two is to bring this understanding to God through repentance.
Step three is, by God’s grace, to stop feeding the flesh and start feeding the spirit on prayer, scripture, Church teaching and Holy Communion.
Step four is to repeat steps 1-3 for the rest of our lives. God by his grace will cause the flesh to die and the spirit to live by his grace at work in us through Jesus Christ.
