We all suffer, including Christians. This is clear by example in Acts 14 as Paul is stoned and dragged outside Lystra, left for dead. Sometimes we suffer because we tell people the gospel. Other times, simply because we live in a fallen world that is ravaged by sin. Occasionally we suffer because God loves us and disciplines those He loves. Our suffering is useful (many times) because it gives us an opportunity to show the world how much more valuable Jesus is than anything we could ever lose (look at Paul in Acts 14!). Our suffering us useful (all the time) because God uses it to make us more like Jesus, the King. We can suffer well as we look to Jesus who suffered and died on a cross. Jesus endured crucifixion not namely as our human example for suffering, but as our Divine Substitute for sin. If you know that Jesus’ death already defeated the only sufferings that can truly harm you, you can suffer well (like Paul, Ridley, and Latimer!). And you can say with Keller, “Come on, crosses, the lower you lay me the higher you raise me! Come on, grave, kill me and all you will do is make me better than before! If the death of Jesus Christ happened for us and he bore our hopelessness so that now we can have hope—and if the resurrection of Jesus Christ happened—then even the worst things will turn into the best things, and the greatest are yet to come.”
