Gentile Times Reconsidered? Are you serious. He needs to reconsider it.
1 Samuel 7
I shall certainly raise up your seed after you, which will come out of your inward parts; and I shall indeed firmly establish his kingdom. 13 He is the one that will build a house for my name, and I shall certainly establish the throne of his kingdom firmly to time indefinite. 14 I myself shall become his father, and he himself will become my son. When he does wrong, I will also reprove him with the rod of men and with the strokes of the sons of Adam. 15 As for my loving-kindness, it will not depart from him the way I removed it from Saul, whom I removed on account of you. 16 And your house and your kingdom will certainly be steadfast to time indefinite before you; your very throne will become one firmly established to time indefinite.”’”
That is a prophesy leading to Christ, starting with Solomon, his descendants were sitting on Jehovah's throne, and one day Jesus would be sitting on Jehovah's throne. But from David, time went by and Jesus never sat on a throne. Infact Jehoiakim became a vassal king subject to Egypt and Babylon and the the kingdom fully fell. It appears that the throne was not firmly established. It seemed as if that prophesy failed; or did it?
No, it didnt' fail, Jehovah just paused it for 7 times or 2520 years and then Jesus was installed as king, not in old Jerusalem which was rejected, but in new Jerusalem which is heavenly.
