But grammatically and theologically, faith and obedience are distinct.
Faith is the means by which we receive God’s grace — not a meritorious work we perform.
Obedience is the fruit or evidence that such faith is real.
Paul carefully separates the two to preserve grace:
“To him that worketh not, but believeth on him that justifieth the ungodly,his faith is counted for righteousness.” — Romans 4:5So while true faith obeys, faith itself is not defined as obedience — it’s trust in God that produces obedience.
Faith obeys; obedience flows from faith.They are inseparable in practice, but not identical in essence.Faith saves apart from works, yet never remains without works.Grace and Peace
I disagree in the sense I use the term disobedient, which is disbelieving and unpersuadeable. Faith is contrasted with disobedience, which logically means faith is obedience.
