"There are two ways to be controlled by sin.  One is to constantly be thinking of participating in it,and the other is to constantly be consumed with staying away from it.  Either way, sin is the focus."

-Michael Wells, Abiding Stories

Takeaway

if you focus on sin (doing it or avoiding it), then sin controls you.  sin and sinning is almost irrelevant for a believer; Jesus Christ is everything, our very life.
Application
it is suitable to focus on Jesus Christ, not on sin.
