This is the Christian life.
This is what grace really comes down to - the ultimate deliverance from struggle.

Gal 2:19  For I through the law am dead to the law, that I might live unto God. 
Gal 2:20  I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 
Gal 2:21  I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
