Some people find it difficult to talk about suffering, perhaps because of bad experiences in their past. Others talk about little else. Hopefully Christian faith finds a balance. But it cannot avoid the subject, because it reflects so much of human experience.
When we come to the first letter of Peter, chapter 3 jumps in at verse 18 (1 Peter 3:18-22 is our reading)
“For Christ also suffered for sins once for all, the righteous for the unrighteous, in order to bring you to God.”1 Pet 3:18
This is suffering with a reason, not some perverted psychology. As Jesus endured undeserved suffering, so Christians do not welcome hardship, but accept whatever comes as part of following their Saviour. You don’t have to enjoy it – it would be a bad thing if you did – but need to understand the possibility.
Then (18b-20) Peter goes on to talk about how Jesus, after his death, preached to the spirits in prison. There are different opinions of what exactly that means: does he  proclaim the gospel to those who died before his ministry, without the chance to hear the gospel, or  announce his victory to the powers of evil? It doesn’t matter too much to us, though we would do well to remember the judgement on those who refuse obedience.
The reference to Noah, and the saving of a handful of people in the ark from God’s judgement on the wickedness of his time, brings us to verses 21,22. Just as Noah’s ark floated people to safety, so Christian baptism is a way of escape to safety. It’s significance is nothing to do with being physically washed, nor is it a magic spell. Baptism applies the power of Jesus victory over evil and his resurrection; it needs faith – and can be disowned by those who do not live by faith – but it remains a powerful sacrament of God’s ownership of those who choose to belong to Jesus.
We may be glad if our lives escape extreme suffering, hopefully remembering those who do not. Perhaps we can try to find the balance between accepting the risks of Christian living, and the joyful celebration of what we are given.
