1 Thessalonians 3:2-4

We sent Timothy, who is our brother and co-worker in God’s service in spreading the gospel of Christ, to strengthen and encourage you in your faith, so that no one would be unsettled by these trials. For you know quite well that we are destined for them. In fact, when we were with you, we kept telling you that we would be persecuted. And it turned out that way, as you well know.
