Galatians 2:20

I have been crucified with Christ (that is, in Him I have shared His crucifixion); it is no longer I who live, but Christ lives in me.  The life I now live in the body I live by faith (by adhering to, relying on, and completely trusting) in the Son of God, who loved me and gave Himself up for me.

If we trust in our salvation and Jesus, we will follow His commandments. Following Jesus opens doors and options of freedom from sin (guilt and condemnation), whereas before Jesus, we were condemned. Our lives are meant for eternity, and we are to live by faith in Jesus Christ.
