Sin

Romans 7:14-25 and 8:1-2

Paul writes about himself:

"For we know that the Law is spiritual, but I am of flesh, sold into bondage to sin. For what I am doing, I do not understand; for I am not practicing what I would like to do, but I am doing the very thing I hate...

For I know that nothing good dwells in me, that is, in my flesh; for the willing is present in me, but the doing of the good is not.

For the good that I want, I do not do, but I practice the very evil that I do not want...

I find then the principle that evil is present in me, the one who wants to do good. For I joyfully concur with the law of God in the inner man, But I see a different law in the members of my body, waging war against the law of my mind and making me a prisoner of the law of sin which is in my body.

Wretched man that I am! Who will set me free from the body of this death? Thanks be to God through Jesus Christ our Lord! So then, on the one hand I myself with my mind am serving the law of God, but on the other, with my flesh the law of sin.

Therefore, there is now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life in Jesus has set you free from the law of sin and death.
For what the law could not do, weak as it was through the flesh, God did in sending his own Son in the likeness of sinful flesh as an offering for sin. God condemned sin in the flesh."

1 John 1:8-9

"If we say we have no sin, we are deceiving ourselves and the truth is not in us. If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness."
