3:8 Many of John's hearers were shocked when he said that being Abraham's descendants was not enough for God. The religious leaders relied more on their family lines than on their faith for their standing with God. For them, religion was inherited. But a personal relationship with God is not handed down from parents to children. Everyone has to commit to it on his or her own. don't rely on someone else's faith for your salvation. Put your own faith in Jesus, and then exercise it every day.
3:8, 9 Confession of sins and a changed life are inseparable. Faith without deeds is dead (James 2:14-26). Jesus' harshest words were to the respectable religious leaders who lacked the desire for real change. They wanted to be known as religious authorities, but they didn't want to change their hearts and minds. Thus their lives were unproductive. Repentance must be tied to action, or it isn't real. Following Jesus means more than saying the right words; it means acting on what he says.
