Verses 42-44 “Therefore keep watch, because you do not know on what day your Lord will come. But understand this: If the owner of the house had known at what time of night the thief was coming, he would have kept watch and would not have let his house be broken into. So you also must be ready, because the Son of Man will come at an hour when you do not expect him.
I’m sorry but this is a commandment to live righteously, because our individual or collective judgment can arrive when we least expect it. That is the full context. We can have some concerns about His return, but it must not be something that occupies us, any more than the lily caring for what it wears on the morrow.
