Jesus did not mean, he did not know when he is coming back.
He was speaking about how he was going to usher the Jews into the new covenant through the marriage of the Lamb. Please read my blog “what no one knows the time and hour mean?”
“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.
It is a Jewish custom for the father of the groom to prepare the house for the bride. It has to beautiful and befitting to usher the new bride.
The son of course being excited would always want it to be as soon as possible. So he ask the father “when can I bring my wife back?”
The father will say “when the room is ready.” He builds an extension to his house but the room has to be perfect. Not for the husband but for the wife.
So he says to the son “only I will know”. So when Jesus said this, he wasn’t saying to them he did not know the time of his coming. He was saying that they were about to leave the old covenant and entered into a new one.
They were about to be separated from their old “husband” and to be married to Jesus their new husband.
It has nothing to do with the timing of his coming. Otherwise Paul would not have written this.
1 Thessalonians 5:1-4
The Day of the Lord
Now, brothers and sisters, about times and dates we do not need to write to you, for you know very well that the day of the Lord will come like a thief in the night.
While people are saying, “Peace and safety,” destruction will come on them suddenly, as labor pains on a pregnant woman, and they will not escape.
But you, brothers and sisters, are not in darkness so that this day should surprise you like a thief.”
How can it be that the Thessalonians knew he was coming and Jesus doesn’t?
Jesus actually knew when he would come. If you bothered to read further in Matthew 24, he actually said it.
Truly I tell you, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away.”
Two things he said.
1. This generation. It will come within 40 years after what Jesus said in Matthew 24.
It will come within that generation he had come to.
2. Heaven and earth passes away. The term “heaven and earth” is a Hebrew colloquial term for the temple.
The temple was destroyed in AD70. 40 years after he said this.
It’s actually very clear here when you take the chapter divisions from the NIV text.
Truly I tell you, this generation will certainly not pass away until all these things have happened. Heaven and earth will pass away, but my words will never pass away.
“But about that day or hour no one knows, not even the angels in heaven, nor the Son, but only the Father.”
Jesus knew exactly when the marriage of the supper of the Lamb would happened.
40 years later. AD70.
This is why I always tell people you need to know the history culture and language of the Scriptures.
