I Thessalonians 3:3

That no man should be moved - That is, caused to apostatize from Christianity. We are appointed thereunto - Εις τουτο κειμεθα· We are exposed to this, we lie open to such, they are unavoidable in the present state of things; as the Latins say, sic est sors nostra, "this is our lot." God appoints nothing of this kind, but he permits it: for he has made man a free agent.

moved--"shaken," "disturbed." The Greek is literally said of dogs wagging the tail in fawning on one. Therefore TITTMANN explains it, "That no man should, amidst his calamities, be allured by the flattering hope of a more pleasant life to abandon his duty." So ELSNER and BENGEL, "cajoled out of his faith." In afflictions, relatives and opponents combine with the ease-loving heart itself in flatteries, which it needs strong faith to overcome. yourselves know--We always candidly told you so (Th1 3:4; Act 14:22). None but a religion from God would have held out such a trying prospect to those who should embrace it, and yet succeed in winning converts. we--Christians. appointed thereunto--by God's counsel (Th1 5:9).

That no man should be moved by these afflictions,.... Which the apostle endured for the sake of preaching the Gospel among them, and which he feared might be a means of troubling their minds, of shaking their faith, and moving them from the hope of the Gospel; for though none of these things moved him, who was an old soldier of Christ, and used to hardness, and an apostle of Christ; yet these were young converts, and not used to such things, and therefore might be staggered at them, and be offended, as stony ground hearers are; and though the apostle hoped better things of them, yet was he concerned for them, that no one among them might be unhinged by them, or succumb under them: for yourselves know that we are appointed thereunto; by the immutable decree of God: afflictions, as to their nature, measure, and duration, are appointed for the people of God, and they are appointed for them; this is the case of all who will live godly in Christ Jesus, and especially of Gospel ministers; of which these saints had been apprized by the apostle, and therefore was nothing new, unheard of, and unexpected, or to be looked upon as a strange thing; and seeing this was the appointment of heaven, and the will of God, they should be patiently endured, and quietly submitted to.

In this chapter the apostle gives further evidence of his love to the Thessalonians, reminding them of his sending Timothy to them, with the mention of his design therein and his inducements so to do (Th1 3:1-5). He acquaints them also with his great satisfaction at the return of Timothy, with good tidings concerning them (Th1 3:6-10). And concludes with fervent prayer for them (Th1 3:11 to the end).

3:3 we are destined for such troubles: Suffering for the faith is often part of a Christian’s life (1:6; 2:14; Phil 1:29; 1 Pet 1:6; 2:21; 3:17; 4:19).
