“Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you. But rejoice insofar as you share Christ’s sufferings, that you may also rejoice and be glad when his glory is revealed.”
-1 Peter 4:12-13
I know this is one of the most difficult things to do as Christian, next on loving your enemies. We are human, and as a human we have emotion, deceitful emotion (Jeremiah 17:9) that can be easily changed based on what we feel. There are times that we forget God either on happiness or sadness but mostly on trials. That is why Peter reminds us that this trials are test but we should not be shaken but remain in faith as we share the same suffering as Christ, those persecution, those temptation and yet in the end, Jesus Christ conquered the world and his glory revealed.
