Jesus would only return to set up His kingdom when Israel repented of their sins, acknowledged their offense, and called on His name: for I tell you, you will not see me again, until you say, ‘Blessed is He who comes in the name of the Lord.’ Matthew 23:39
Unbelieving Israel
Here was the God of life and glory, sent to redeem His own precious people, and He had to turn away bearing the precious gifts He wanted to bestow - the kingdom of God shall be taken from you, and given to a nation bringing forth the fruits thereof. Matt 23:39 For I say unto you, ye shall not see Me henceforth, till ye shall say, 'blessed is He that comes in the name of the Lord.'” Matt 21:43
