"As for other matters, brothers and sisters, we instructed you how to live in order to please God, as in fact you are now living. Now we ask you and urge you in the Lord Jesus to do this more and more." — 1 Thessalonians 4:1
Paul is commending the people of this church for following God in the way they live. They are showing faith and love and hope. They are caring for others. They are listening to and obeying the Word of God, despite persecution. They are resting in the hope of Christ’s return. Yet, he still implores them to do this more and more. In 3:10 Paul tells them, after applauding their faith, that he would like to see them again and "supply what is lacking in your faith." If they are living for God and loving as Christ would and have faith, what does Paul mean that something is lacking? Let’s look at an example.
