I have discovered this principle of life—that when I want to do what is right, I inevitably do what is wrong.  I love God’s law with all my heart.  But there is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me.  Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death?  Thank God! The answer is in Jesus Christ our Lord.
- Romans 7:21-25

So now there is no condemnation for those who belong to Christ Jesus.  And because you belong to him, the power of the life-giving Spirit has freed you from the power of sin that leads to death. 
- Romans 8:1-2
