“That no man should be moved by these afflictions: for yourselves know that we are appointed thereunto. For verily, when we were with you, we told you before that we should suffer tribulation; even as it came to pass, and ye know.” 1 Thessalonians 3:3-4 KJV
You should know such troubles are a part of God’s plan for us Christians.
Paul says, I sent Timothy, “our brother, and minister of God, and our fellowlabourer in the gospel of Christ, to establish you, and to comfort you concerning your faith: That no man should be moved by these afflictions: for yourselves know that we are appointed thereunto.” 1 Thessalonians 3:2-3
Not that you get a false sense of peace but to comfort you concerning your faith that you never give up. “…we glory in tribulations also: knowing that tribulation worketh patience; And patience, experience; and experience, hope.” Romans 5:3
Philippians 1:27-30 says,
 Only let your conversation be as it becometh the gospel of Christ: that whether I come and see you, or else be absent, I may hear of your affairs, that ye stand fast in one spirit, with one mind striving together for the faith of the gospel;  And in nothing terrified by your adversaries: which is to them an evident token of perdition, but to you of salvation, and that of God.  For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;  Having the same conflict which ye saw in me, and now hear to be in me.
