In practice, the Universal Church (all the redeemed of all the ages) has never seen a time without fiery ordeals. There have been seasons and locations of ease, like many years in the United States have been, but always there have been members of the family of faith who could not lightly hold their confession. As those seasons and locations of safety shift, it is worth asking ourselves the same question: Would you rather be blessed for being reviled for Christ, or be comfortable?
4:18 echoes Proverbs 11:31. And note that throughout, Peter is still more focused on encouraging and challenging the church to be like Jesus and fulfill His call than he is on helping them avoid trouble.
