I l8ke the word trust better than faith. Trust is something you do with your heart, not just a one time prayer for salvation. True salvation is obedience.
If you want to make that distinction, to the degree your “trust” is your own self effort, to that degree your self-effort of “trust” doesn’t save you whereas you are saved BY GRACE THROUGH FAITH (Galatians 5:4.). (Faith is an undeserved gift from God and grace is UNDESERVED favor of God.)
Jesus took care of the obedience problem. Your flesh and mine will NEVER be obedient and will NEVER solve the sin problem. Otherwise, Jesus died in vain. But he didn’t. Jesus on the cross solved all.
That is why the word says GRACE and TRUTH came by Jesus Christ (NOT THE LAW and truth). Jesus fulfilled the law so we are under the New Covenant of Grace which has replaced the Old Covenant of the law (Hebrew Chapters 8 & 10).
