Keep awake for you know neither the day nor the hour when Jesus would come.
1. We do not know when would Jesus come for his second coming.
2. When He comes will he find our lamp on fire? The fire in our lamp signifies our good deeds. The oil signifies our love for God and others.
3. We don't want the door of Heaven to be closed on us and hear Jesus tells us that He doesn't know us for our lack of good deeds.
