We come to the prophesied judgment of nations at the end of the Great Tribulation period.
During the seven years of 'the time of Jacob's Trouble', those who believe God will demonstrate their faith by showing kindness and protection to the 'brethren' of Jesus Christ. And we have seen that this refers to the natural, blood relation of Jesus, the son of Mary of the tribe of Judah AND of those who are grafted into the promises of salvation by faith in Jesus as Messiah. (Paul uses this same dual designation--see Acts 28:17 and Romans 1:13, for example.)
After a look at this Judgment of the Nations, we will also look at the King of Peace who will rule over the holy city of Jerusalem during a Millennial Kingdom. The King of kings is none other than Jesus Christ of Nazareth.
