We will never know which day he will return.
Matthew 24:36-44 "However, no one knows the day or hour when these things will happen, not even the angels in heaven or the Son Himself. Only the Father knows.
37 "When the Son of Man returns, it will be like it was in Noah's day. 38 In those days before the flood, the people were enjoying banquets and parties and weddings right up to the time Noah entered his boat. 39 People didn't realize what was going to happen until the flood came and swept them all away.
That is the way it will be when the Son of Man comes. 40 "Two men will be working together in the field; one will be taken, the other left. 41 Two women will be grinding flour at the mill; one will be taken, the other left. 42 "So you, too, must keep watch! For you don't know what day your Lord is coming.
43 Understand this: If a homeowner knew exactly when a burglar was coming, he would keep watch and not permit his house to be broken into. 44 You also must be ready all the time, for the Son of Man will come when least expected.
It has been a while since a religious group made the news with their prediction that Jesus is going to return by a set time, I am sure that somebody else is going to take a stab at it but why, how could they possibly know?
Don't they know that the odds are stacked against them? Why do they want to take on Jesus, when he says that nobody can possibly figure out when he will return, he means that NOBODY will know when. Jesus told them that if they expected it to happen at a specific time then guess what, that certainly isn't the time.
I am sure that Noah told everybody that asked why he was building that big boat, he must have been asked a thousand times, and as they walked away laughing not one of them was concerned with God's coming judgment. It is more probable that they were placing their bets on when the rain would start.
I am ready for his return and I hope that you are also ready.
