"A person is put right with God only through faith in Jesus Christ, never by doing what the Law requires. We, too, have believed in Christ Jesus in order to be put right with God through our faith in Christ, and not by doing what the Law requires. For no one is put right with God by doing what the Law requires."

(Galatians 2.16 GNB)

The Law mandates obedience.
But I can obey and not have faith.
Faith requires trust from deep within
the heart and mind and soul.

If I have faith,
I consequently want to obey
the God that I trust.

See: Trust vs obey
