1 Thessalonians 3:1-5

When we could bear it no longer, we decided that we would remain in Athens and send Timothy in our place. He is our beloved brother and coworker with God in preaching the gospel. We knew he would strengthen your faith and encourage your hearts so that no one would be shaken by these persecutions, for you know that we are destined for this. In fact, when we were with you we forewarned you: “Suffering and persecution is coming.” And so it has happened, as you well know. For this reason, when I could endure it no longer, I sent our brother to find out if your faith was still strong, for I was concerned that the tempter had somehow enticed you and our labor would have been in vain.
