Silas had laid down his life for the name of Christ (Acts 15:26).
The decision brought joy to the churches. They encouraged and strengthened churches as they took and read the letter.
The completeness of the resolution to this conflict is remarkable. There is no hint from either side that the decision was in any way inadequate! Wow!
As a result of this conflict and the one at the end of the chapter between Barnabas and Paul, the Holy Spirit directed the church into ways new places and new leaders were raised up. It is so easy to see conflict as always bad, but God uses it in great ways. Silas gained invaluable experience carrying the letter, watching the debates and having responsibility with Paul.
