Two Greek adjectives were translated as 'good'. Kalos had an aesthetic connotation, while agathos had a stronger moral and ethical dimension. Jesus was saying that true goodness (implied agathos) originated from within a person and was manifested in their outward actions and words (kalos).

Applying the context of the Pharisees (v 24), they looked good externally but not internally.

Mt 23:

27 Woe to you, scribes and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside, but on the inside are full of dead men’s bones and every kind of impurity.

καλός-good (BDAG καλός ②) life came from a ἀγαθός-good (BDAG ἀγαθός ②) heart/wisdom, exhibiting καλός-good deeds. James used καλός here instead of ἀγαθός because he wanted to emphasize the showing or demonstration of a good life. Here, the distinction between these two words of 'good' was subtle. Unfortunately, the English word 'good' cannot separate these nuances.
