How can Jesus and Peter says such a ridiculous thing?
How can you rejoice when you are insulted or mocked? When your own children are threatened or abducted? When you are imprisoned and not able to be with or to provide for your family?
But rejoice that you participate in the sufferings of Christ, so that you may be overjoyed when his glory is revealed. If you are insulted because of the name of Christ, you are blessed, for the Spirit of glory and of God rests on you. (1 Peter 4:13,14)
