1 Thessalonians 2:16

forbidding us to speak to the Gentiles that they may be saved; to fill up their sins always [Genesis 15:16; Matthew 23:32]: but the wrath is come upon them to the uttermost. [While narrating the course of events at Thessalonica, Paul notes the similarity between the history of the Thessalonian church and that of the Judæan churches, and reviews the latter history for the encouragement of the Thessalonians. Surely the opposition of their pagan countrymen ought not to cause these Thessalonian Christians to doubt that God favored or approved them, for such opposition was to be expected. Even the Jews, though professedly the people of God, had killed God's prophets and Christ their Lord, and had driven out the apostles and evangelists. Though the Jews were God's people, their conduct in rejecting God's Son showed that they did not please God; and that they were haters of their fellow-men was very apparent, for they even forbade Christ's apostles to attempt to save the Gentiles by preaching the gospel to them. Their opposition to churches either in Judæea or Greece was therefore no evidence that God disapproved these churches: on the contrary, God patiently permitted them to do all this, that their wickedness might be fully ripened and exposed, so that a full and notable punishment might be meted out to them--punishment which began just before the siege of Jerusalem, and continues to this day. Wrath unto the uttermost, or unto the end, signifies a wrath which fully expends itself in executing judgment. It does not mean wrath unto the end of the world-- Romans 11:15; Romans 11:25-26]
