go with them, doubting nothing; for I have sent them.”
The success of the mission to Cornelius’ house had less to do with Peter’s ability to speak and more to do with the audience’s ability to hear. When we speak only to whom we are sent then we will see dramatic results.
Trying to speak to everyone in general and no one in particular is a colossal waste of time and demonstrates poor stewardship. We ought not to give ten coins to someone who can only handle five, and we ought not to give five coins to someone who cannot handle even one. It is clear that much time is wasted trying to convince, persuade, plead, argue, teach, and help people to whom God has not sent us. If we will wait for the Spirit of God we will save ourselves a lot of time, effort and energy. A worker who indiscriminately throws precious seed on rocky ground and gives pearls to pigs is not being a wise, faithful, and profitable servant.
