Metanoia encompasses both attitudinal and behavioral change; Luke 3:8 and Acts 26:20 illustrate the distinction.

The focus of metanoia varies by context: sometimes it is mental/attitudinal (a change of mind), sometimes behavioral. Luke 3:8: "bear fruits in keeping with repentance" — repentance as attitude producing fruit. Acts 26:20: "they performed deeds in keeping with their repentance" — the mental change leading to life change. Grief is what leads to repentance, not the act itself.
