Actually, the final command was more precise than that. He did not say, “Teach them all my commandments.” He said, “Teach them to observe all my commandments.” You can teach a parrot all of Jesus’s commandments. But you cannot teach a parrot to observe them. Parrots will not repent, and worship Jesus, and lay up treasures in heaven, and love their enemies, and go out like sheep in the midst of wolves to herald the kingdom of God. Teaching people to parrot all that Jesus commanded is easy. Teaching them to observe all that Jesus commanded is impossible. Jesus used that word. When a rich man could not bring himself to let go of his riches and follow him, Jesus said, “It is easier for a camel to go through the eye of a needle than for a rich person to enter the kingdom of God. . . . With man it is impossible, but not with God. For all things are possible with God” (Mark 10:25–27).
