Jesus says that exhortations to "watch" apply to everyone (Mark 13:35-37). In this case, the parable that follows shows that the apostles have a special responsibility. In it, the steward in charge of the servants is a servant himself, teaching the importance of faithfulness in doing the will of the master (I Corinthians 4:2). Not only does Jesus teach the certainty of His return at an unexpected moment, but he also implies that the church - His disciples - would continue serving God for an unspecified time until His return. As He says, "Blessed is the servant whom His Lord will find so doing when He comes."
