Obedience is the fruit of faith.

The aphorism frames obedience not as mere external compliance but as a natural outgrowth of inward trust. In Christian moral theology, “faith” is the root disposition—confidence in God’s character and promises—while “obedience” is the lived expression that follows from it. Read this way, the line resists legalism (obedience as a way to earn favor) and instead presents ethical action as evidence of belief’s vitality. It also implies an organic sequence: where faith is genuine, obedience ripens as its “fruit,” suggesting both growth over time and a test of authenticity.
