Acts 18:5
And when Silas and Timotheus were come from Macedonia, Paul was pressed in the spirit, and testified to the Jews that Jesus was Christ. And when Silas and Timotheus were come from Macedonia, Paul was pressed in the spirit, and testified to the Jews that Jesus was Christ.
The verse places Paul at Corinth, laboring both in word and doctrine and in the workshop, at the moment when Silas and Timothy arrived from Macedonia to join him. His message to the Jews there was direct testimony that Jesus is the Christ, the promised and long-awaited Messiah. He proved this from Moses and the prophets, reasoning that the Messiah was to descend from Abraham and David and that the prophecies concerning his character and work were fulfilled in the life, ministry, and death of Jesus. His teaching presented the death of Jesus as fulfilling the meaning of the Jewish sacrifices by making atonement for sin once for all, and his ministry as humanity's great High Priest in the heavenly sanctuary as the reality foreshadowed by the Jewish priesthood. His preaching centered on Christ and the cross, relying on God's grace rather than persuasive oratory or philosophical argument, and it had a powerful effect.
The arrival of Silas and Timothy greatly cheered Paul because they brought good news of the faith and love of the Thessalonian believers, who had remained faithful to God through trial and hardship. Their meeting gave him fresh zeal and courage while he was in weakness and in fear and in much trembling, to withstand continually increasing opposition that had greatly hindered his labors, showing God's comfort for those who are cast down through the arrival of friends. It reveals God's design that fellow laborers in the gospel have their hearts knit closely together in the bonds of Christian love so that their presence greatly cheers and encourages one another. His teaching about Jesus as the Messiah provoked opposition from the Jews, and after their rejection of the message he turned to the Gentiles, after which Silas and Timothy labored together with him for the Gentiles.
At Corinth he preached the truth to those in the darkness of error and labored a year and six months, proving the divine character of his mission by raising up a flourishing church composed of Jews and Gentiles. The Gentile converts were more numerous than the Jewish converts, and many were truly converted and brought from darkness into the light of the gospel, since the Gentiles were in a more favorable condition than the Jews to receive the truth because they were not walled in by the maxims and traditions of priests and elders. His work shows that gospel labor is to reach beyond established churches and into the wider world, for God is hungry for fruit and calls workers to branch out more than they are doing and make the world their field of labor rather than working for the churches only. That work at Corinth later included confusion and strife spread among the church there by others, which Paul mentioned when he later gave an account at Jerusalem of what God had wrought among the Gentiles by his ministry, relating it with great gentleness and courtesy, avoiding everything that would unnecessarily wound his brethren and dwelling especially on topics where they could harmonize.
