The parables concern the returning Lord Jesus. He will soon be taken away from his disciples, but he will return, although when we least expect it. Only the prepared disciple will share in Christ's Kingdom on that day. The perseverance of the saints One of the more fascinating doctrines of the Christian faith is the perseverance of the saints. The doctrine deals with the continuation of our salvation.
Most believers tend to worry about their future salvation.
A believer who takes an Arminian theological position, who believes that their salvation is dependent on the quality of their response to Christ, today and everyday following, is naturally bound to question the worth of that response. A believer who takes a Calvinist theological position, who believes that their salvation is dependent on the sovereign predestined will of God, is no better off. They can never be sure that their piety evidences a genuine salvation. Jesus warns us that we must remain watchful, ready, for he will return when we least expect it. Some argue that the image Jesus uses here is of faithful service.
