Repentance is primarily a change of heart, confirmed by fruits, good works. John the Baptist addressed the need to change our hearts and our deeds. We see John’s concerns even today, exploitation of taxes for personal gain and misuse of military might to enrich ourselves. Baptism is confirmed in a decision to repent. Baptism by fire is threefold: a baptism by fire occurred as flames of fire resting upon people’s heads on that first Pentecost, a baptism by fiery trials and judgment to come in which the “chaff” will be burned with unending fire. Hell “fire and brimstone” preaching can easily be overdone or ignored completely. Yet, Jesus does preach about final judgment in fire. He also appeals to us to repent so that we don’t have to face it.
