What should be the effect and fruit of true faith in the Christian?
True and saving faith always yields fruits “worthy of repentance” (Luk 3:8; see Q376) and of our life in Christ (Gal 5:22–26; see Q211, Q237). The Lord’s teaching is clear: “every good tree bears good fruit… you will know them by their fruits. Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father in heaven… Then I will declare to them: ‘I never knew you; depart from me, you evildoers’” (Mat 7:17–23).
This is also the apostolic teaching of St Paul: “in Christ Jesus, neither circumcision nor uncircumcision has any value, only faith working through love” (Gal 5:6; see Q078, Q480).
