"By this shall all men know that ye are my disciples, if you have love one to another" John 13:35. The church at Thessalonica had mastered loving one another. They were so committed to praying for one another, helping each other in times of tribulation and persecution, and persevering in the faith, that ALL of Macedonia had heard of their deep and abiding love for Christ and their brothers and sisters in faith. What does it mean to practically to love one another? Paul spells it out in I Thessalonians 4:9-12
