1. We are destined for persecution (1-5)
Paul longed to see the spiritually young believers in Thessalonica. He had taught them that persecution and suffering would accompany their new faith in Christ. This is, in fact, what happened. Paul was afraid that the devil used these trials to tempt these young believers to give up their faith. When Paul could find no way to go himself, he sent Timothy to strengthen and encourage them. Persecution from a hostile world is inevitable for true Christians.
2. Stand firm in the Lord (6-13)
Timothy returned with a glowing report. The Thessalonians were full of faith and love. They also longed to see Paul. The Lord had helped them to stand firm in their faith. Paul prayed for God to meet their needs, for their love to increase and for their hearts to be strengthened. His hope was for them to be holy and blameless at Jesus' return.
