Paul said Timothy and him were like-minded. They speak the same message. Ask God to show you who are the genuine spiritual sons and daughters
Philippians 2:19-22 If the Lord Jesus is willing, I hope to send Timothy to you soon for a visit. Then he can cheer me up by telling me how you are getting along. I have no one else like Timothy, who genuinely cares about your welfare. All the others care only for themselves and not for what matters to Jesus Christ. But you know how Timothy has proved himself. Like a son with his father, he has served with me in preaching the Good News.
You can send someone who thinking it’s a good opportunity for his own ministry, someone who is self serving. You go to outreach because of the need that God has revealed to you.
