For what thanksgiving can we render again to God for you, for all the joy with which we rejoice for your sakes before our God;
Paul was there in Athens waiting for Silas and Timothy to arrive. He was discouraged. When Timothy came, he was concerned about the church of Thessalonica. "We were there such a short time. Go back Timothy. I'm gonna go on down to Corinth; you go back and find out how they're doing." So, "When I couldn't take it any longer, I was so concerned about you, worried and concerned for you, I sent Timothy our brother that he might establish you and comfort you concerning your faith."
