Greetings from Paul, Silas, and Timothy. To the church (group of believers) that lives in Thessalonica. That church is in God the Father and the Lord Jesus Christ. {God's} grace (kindness) and peace be yours.
When we pray to God our Father we always thank him for the things you have done because of your faith. And we thank him for the work you have done because of your love. And we thank him that you continue to be strong because of your hope in our Lord Jesus Christ.
