Consider it all joy, my brethren, when you encounter various trials, knowing that the testing of your faith produces endurance. And let endurance have its perfect result, that you may be perfect and complete, lacking in nothing. (James 1:2-4)

"Blessed are those who have been persecuted for the sake of righteousness, for theirs is the kingdom of heaven. "Blessed are you when men cast insults at you, and persecute you, and say all kinds of evil against you falsely, on account of Me. "Rejoice, and be glad, for your reward in heaven is great, for so they persecuted the prophets who were before you." (Matthew 5:10-12)

Blessed is a man who perseveres under trials; for once he has been approved, he will receive the crown of life, which the Lord has promised to those who love Him. (James 1:12)

But to me it is a very small thing that I should be examined by you, or by any human court; in fact, I do not even examine myself. I am conscious of nothing against myself, yet I am not by this acquitted; but the one who examines me is the Lord. (1 Corinthians 4:3-4)

Who is there to harm you if you prove zealous for what is good? But even if you should suffer for the sake of righteousness, you are blessed. And do not fear their intimidation, and do not be troubled, but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence; and keep a good conscience so that in the thing in which you are slandered, those who revile your good behavior in Christ will be put to shame. For it is better, if God should will it so, that you suffer for doing what is right rather than for doing what is wrong. For Christ also died for sins once for all, the just for the unjust, so that He might bring us to God. (1 Peter 3:13-18)

Do you not know? Have you not heard? The Everlasting God, the Lord, the Creator of the ends of the earth does not become weary or tired. His understanding is inscrutable. He gives strength to the weary, and to him who lacks might He increases power. Though youths grow weary and tired, and vigorous young men stumble badly, yet those who wait for the Lord will gain new strength; They will mount up with wings like eagles, they will run and not get tired, they will walk and not become weary. (Isaiah 40:28-31)
