The Thessalonians were facing persecution, they were being targeted by false teachers, and they were young Christians newly founded in the faith. In 2 Thessalonians 2:16-17, Paul puts the capstone on what they needed to remember. They need to remember Christ, remember the grace of the Father, remember the comfort of God, remember the strengthening work of God, and remember the calling God had given to them. We as Christians need these reminders in the multi-faceted trials we face over the course of our lives. May God strengthen us through His Word to be faithful!
