Acts 13:3 Then, having fasted and prayed, and laid hands on them, they sent them away.
The early Christians were doing what they could to follow Christ and His ways. They had listened to and learned from Jesus their teacher and Messiah.
Now they were acting out the teachings in the ways of Christ. Simply telling someone to go out and do things because it seems like a good idea may not be what Christ wants.
In order to put aside our selfish ambitions we have to stop and listen to God; often that will entail us doing a bit more praying and listening but also putting aside our earthly pleasures to focus on God’s will instead of our own.
