Jesus was asked by the Pharisees when the kingdom of God will come. He answered “You won’t be able to see when the kingdom of God comes because it is among you.”
Then he spoke to the disciples. “Soon you will miss days like this, where the Son of Man is among you. People will say ‘Look there!’ or ‘Look, here is the Messiah!’ Don’t listen to them or go where they show you. False messiahs and false prophets will gain prominence and will mislead a lot of people by performing great signs and wonders. Even the elect are at risk of being led astray by them.”
“I’ve told you everything in advance so that you can be on your guard. This way if they say ‘Look he’s in the wilderness’ or ‘He’s in the inner rooms’, you’ll know not to believe what they say and you’ll stay where you are.”
“The Son of Man will come in the same way that lightning flashes from one side of the sky to the other, lighting it all up.”
