When an American Robin goes for an earthworm burrowing into the soil, the worm’s natural reflex is to eject its tail. So when the Robin pulls, it loses the tug-of-war. The worm remains safe and, over time, regrows its tail.
Have you ever found yourself in a struggle? Did you feel a bad choice yanked you in one direction, and the right choice held on tight? In the tug-of-war between wrong and right, be an earthworm–let go of the sin and replace it with a clean, fresh right choice.
If your hand causes you to stumble, cut it off. It is better for you to enter life maimed than with two hands to go into hell, where the fire never goes out. Mark 9:43
