Paul picked up where he left off in the first letter; clearing up their misundertandings about Jesus' return, and encouraging them to faith-filled living.
Living by faith and love called for steadfastness and perseverance. Was it worth it? What about those who were making life miserable for Jesus' followers? Would God deal with these matters righteously? Knowing that He would, Paul encouraged them to stay the course with thoughts like these. Your suffering clearly indicates that God will render judgment. God will turn the tables: you will have relief and they will be afflicted. God will be glorified in you on that day.
As encouraging as these promises were, we need to "sort them out." Many have mis-timed them. If their assertions are accurate, those poor Thessalonians are still awaiting relief. What a comfort that must have been for them!
