Matthew 3:8

When John realized that a lot of Pharisees and Sadducees were showing up for a baptismal experience because it was becoming the popular thing to do, he exploded: “Brood of snakes! What do you think you’re doing slithering down here to the river? Do you think a little water on your snakeskins is going to make any difference? It’s your life that must change, not your skin! And don’t think you can pull rank by claiming Abraham as father. Being a descendant of Abraham is neither here nor there. Descendants of Abraham are a dime a dozen. What counts is your life. Is it green and flourishing? Because if it’s deadwood, it goes on the fire.
