You are asking about a strong and harsh sentence that concludes Jesus' Parable of the Pounds in Luke 19. I've already written, in a previous “Interpret This” message, about the parable itself, in the more familiar version from Matthew (25:14-30), known as the Parable of the Talents.
The basic story is the same in both versions. A wealthy master (Luke makes him a nobleman) goes on a long trip after first entrusting large sums of money to each of three different servants. When he returns, he calls each servant to account for the sum with which he has been entrusted. Two of the servants have wisely invested the sums, and are rewarded accordingly. The third servant, fearful of what might happen if he were to lose the money, keeps it hidden and is able only to return exactly what he was given. As a result, the amount he had been given is taken away and given to the other servants.
The metaphysics of that basic story are clear and powerful. Each of us is entrusted with certain “talents” according to the unique expression of Christ energy that is our true identity. We are here in human form to “invest” those talents—to use them as a means of expanding the kingdom of heaven by bringing more Christ energy—more of God—into expression. We do this with confidence and love, fully trusting in our relationship to Source. If we allow fear to block this creative process, as the third servant did, we remove ourselves from the flow of divine empowerment. Our fears will create a life experience of greater and greater fear; we will lose even what we have.
Luke adds a dramatic framework to the story, which leads to the sentence you're asking about. In the nobleman's absence, some people who hated him tried to overthrow his rule. Upon his return, the nobleman deals with them harshly: "But as for these enemies of mine, who did not want me to reign over them, bring them here and slay them before me."
Allowing for a certain artistic license—Luke was, after all, a master storyteller with a fine appreciation of a dramatic finish—there is, I think, an important metaphysical point that can be taken from this elaboration. The fearful servant made a fearful choice. His “punishment” is not really punishment at all; it's simply an expression of the spiritual truth that choices have consequences. His fearful choice results in a fearful life experience. His fear of lack results in an experience of lack. But he is free to learn from that experience and to make in the future more positive, loving, affirmative choices that will result in a vastly improved life.
The rebellious citizens simply refuse to accept the law of the land. They are not willing to make mistakes, and to learn, and to prosper by cooperating with divine law. That kind of willfulness is very dangerous. The Power of God as Law expresses with infinite love whenever we choose to cooperate with it—to learn, to grow, to make new choices. But if we insist on resisting, on angrily refusing to obey the overriding law of the universe, then the outcome can only be destruction and death. By refusing to embrace the guidance of God as Law, we close ourselves off from God as Love. Since we recognize all these biblical characters as aspects of our own consciousness, we can see that those angry, rebellious, egocentric thoughts refusing to recognize or follow a larger spiritual purpose are the most dangerous and deadly thoughts in consciousness.
