Apostle Paul love the church at Thessalonica and he and the brothers did not want to leave but it was nessiceary. Yet, when he got the chance he would write the church to encourage them and remind them they all love the infant church fron day one. The church at Thessalonica was a young church if you look at it in the natural as a human being it would be a infant. Apostle Paul and the brothers love Thessalonica they saw this church apply the word of God which was taught to them by Paul and the brothers. Te young church went through somethings  yet they stood on the word that was taught because they were determine to survive as a church of God.
