Why is true goodness important for Christians?

Christian goodness cannot be distilled to mere moral behavior; it stems from a heart transformed by God's sovereign grace. As seen in Matthew 12:35, a good person, guided by a new heart, produces good things. This goodness displays the fruit of genuine faith and the indwelling of the Holy Spirit. Christians are called to glorify God through their actions and speech, which should reflect their reliance on Christ as their righteousness. Therefore, true goodness is crucial in distinguishing genuine believers from those who merely profess faith without evidence of transformation.
