Luke 3:9

9 You are like trees that have bad fruit. God has an axe ready to use. He will cut down every tree that does not make good fruit. He will throw those trees into the fire.’

3:8The Jews knew that they were God's special people. But how they lived was important to God. God wanted them to live good lives. At that time, many of them did not seem to understand that. When they did not obey him, he was angry with them. He was ready to punish those people, if they would not obey him.
3:8The Jews called themselves ‘children of Abraham’. God had used Abraham many centuries before to start their family.
