Acts 15:22 Then it pleased the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas, namely, Judas who was also named Barsabas, and Silas, leading men among the brethren.
A big part of our lives with Christ is being able to share the gospel with others; and this is not just to those around us but to all the world.
It is not possible for us to announce the gospel in person to the whole world, but we can send others out to do that bidding for and with us!
As churches we need to acknowledge the need for others to go out in our name and share the good news; that means they will need our support!
