1 Thessalonians 3:1-5

Therefore, when we could no longer endure our separation [from you], we thought it best to be left behind, alone at Athens, and so we sent Timothy, our brother and God’s servant in [spreading] the good news of Christ, to strengthen and encourage you [exhorting, comforting, and establishing you] in regard to your faith, so that no one would be unsettled by these difficulties [to which I have referred]. For you know that we have been destined for this [as something unavoidable in our position]. For even when we were with you, we warned you plainly in advance that we were going to experience persecution; and so, as you know, it has come to pass. For this reason, when I could no longer endure the suspense, I sent someone to find out about your faith [how you were holding up under pressure], for fear that somehow the tempter had tempted you and our work [among you] would prove to be ineffective.
