Mark 13:32-36

“No one knows when that day or time will be, not the angels in heaven, not even the Son. Only the Father knows. Be careful! Always be ready, because you don’t know when that time will be. It is like a man who goes on a trip. He leaves his house and lets his servants take care of it, giving each one a special job to do. The man tells the servant guarding the door always to be watchful. So always be ready, because you don’t know when the owner of the house will come back. It might be in the evening, or at midnight, or in the morning while it is still dark, or when the sun rises. Always be ready. Otherwise he might come back suddenly and find you sleeping.
