1 Peter 3:18-22
Written to believers in Rome who were under the Great Persecution, the first letter of Peter was written to encourage them in their faith in Jesus Christ. The passage demonstrates that we can live with the suffering we experience as we remember the persecution Christ endured on our behalf. In other words, there is nothing that we experience now that can compare to what Jesus endured. That is a truth but it is not helpful when we are enduring pain, sorrow, grief, and turmoil in our circumstances.
Instead, I think we need to view the passage in three ways:
Suffering – who needs it? We all do, if for no other reason than to ground us in our faith, reminding us of the power of our baptism into that faith and that we are connected to Christ for all time and space.
