The kingdom of God will be taken from you and given to a nation bearing the fruits of it.
Israel after the flesh was to be put aside. The kingdom for which they had waited so long was to be lost to them forever. A new and elect nation, a regenerated Israel, shall possess the kingdom eventually. Meantime the grace of God is going out to the Gentiles.
It is a terribly dangerous thing to trifle with the mercy of God. Little did the Jewish leaders realize that they were sealing their own doom in rejecting Jesus, the One sent of God to bring them into fullness of blessing if they had received Him. They lost their opportunity because they were blinded by self-interest and so they failed to recognize their Messiah when He came in exact accord with the Scriptures of the prophets which they professed to reverence. Mere knowledge of the letter of the Word saves no one. It is those who believe in the Christ of whom the book of God speaks who are made wise for salvation (2 Timothy 3:15). To reject Him is fatal.
What will you do without Him,
When He has shut the door,
And you are left outside, because
You would not come before?
When it is no use knocking,
No use to stand and wait,
For the word of doom tolls thro’ your heart,
That terrible “Too late!”
