1 Thessalonians 3:1-3 NIV

[1] So when we could stand it no longer, we thought it best to be left by ourselves in Athens. [2] 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, [3] so that no one would be unsettled by these trials. For you know quite well that we are destined for them.
