At least Jesus' disciples got it, which is more than can be said for some folks around here.
Well let's see what Jesus' disciples did get. Let's review what we have so far:
After "forty days, and speaking of the things pertaining to the kingdom of God ... and when they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power."[Acts 1]
Then after this in Acts 3 after being filled with the Holy Spirit, Peter declares to the Jews:
"But those things, which God before had shewed by the mouth of all his prophets, that Christ should suffer, he hath so fulfilled. Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord. And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began."[Acts 3]
And then later at the first council of the church in Jerusalem comes this declaration:
"Simeon hath declared how God at the first did visit the Gentiles, to take out of them a people for his name. And to this agree the words of the prophets; as it is written, After this I will return, and will build again the tabernacle of David, which is fallen down; and I will build again the ruins thereof, and I will set it up: That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things." [Acts 15]
So we have the restoration of the kingdom to Israel yet future in Acts 1, the restitution of all things [that the Jewish prophets said would be restored] in Acts 3, and the restoration of Jerusalem [the capital of the Kingdom of Israel] in Acts 15.
Does that sound to you like God has forgotten his promises to restore the kingdom to Israel???
