The fact that an act falls under destiny does not provide an automatic excuse for committing it. The servant does not know in advance what choice he will make. Religious obligations require him to pursue what is right, avoid what is forbidden, and correct his conduct when he errs.
Suppose someone breaks a promise and then says, “It was decreed.” The event's inclusion within divine decree does not change its moral ruling. By contrast, remembering destiny in an unavoidable misfortune can support patience and acceptance of what has occurred.
Thus recognizing that an event was decreed differs from evading responsibility for a voluntary wrong. The distinction is a direct practical implication of the passage's treatment of accountability.
