We loved you dearly. Not content to just pass on the Message, we wanted to give you our hearts. And we did. 1 Thessalonians 2:8 MSG
God had put His hand on Paul so that Paul went through trouble but was used powerfully. That means the power and piercing love of the Holy Spirit flowed and moved others to know Him.
Somehow God had put His hand on the Thessalonians in a similar way to Paul. And Paul seemed to be comforted and encouraged by what they had in common. A warm, strong love was formed between Paul and these people because of their common love for the people of the world and Message of God.
