What the Bible says about gods purpose in suffering

1 Peter 4:12-13

Beloved, don’t be astonished at the fiery trial which has come upon you, to test you, as though a strange thing happened to you. But because you are partakers of Christ’s sufferings, rejoice; that at the revelation of his glory you also may rejoice with exceeding joy.

2 Corinthians 12:9-10

He has said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ’s sake. For when I am weak, then am I strong.
