Luke 1-3

When the crowds came out to John they heard a message in the spirit of the Old Testament prophets; a message of repentance. Like those earlier prophets there needed to be something more that a verbal acknowledgment of who God is. John said that God demanded changed lives. In Luke 3:7 he compared the stones near where the people were to the children of Abraham. How were they similar?
1. Stones don't change on their own. Once the forces of nature create them a stone remains pretty much unchanged until something else begins to reshape it. Wind, water, rain, and chisel are just some of the external influences that bring change to stones. The children of Abraham who stood before John didn't want to change, and they could not change on their own.
2. Stones don't move by themselves. Where they lie there they will stay until something influences them. Once again it takes wind, water, plow, or hands to change the location of a stone. The children of Israel didn't want to move from where they were; even if God wanted them to move.
3. Stones don't speak for themselves. They carry no message until someone inscribed on their surface words that make sense, or groups and arranges them into a message on the ground. The sons of Abraham thought they had God's message but they didn't understand that God wanted to give that message to the world.
