A commentary on Paul's earliest letter is always a good thing to have. In this commentary, the author highlights that 1 Thessalonians is a love letter just like Philippians. In chapter 2 verse 8 Paul writes: 'We loved you so much that we were willing to share not only the gospel of God, but also our lives.' This verse was a living reality to me when I was a member of All Souls Langham Place. There, I had Christians participate in my life by sharing not only the gospel of God but also their lives. Sharing the gospel is sharing the gift of self, and unless you're giving of yourself in Christian fellowship you are not sharing the gospel at all. The commentator, Leon Morris, goes on to say that sharing your life with other Christians is a way of them supplying what you lack in your faith, and you supplying what they lack in their faith. If you are not growing in your faith at church then it is usually because Christians are not sharing their lives with you to prevent you from falling short of where you should be. This is why Christians must increase in love for each other so that they can help each other grow in their faith.
