What does the Bible say about Christ sending preachers?

In Mark 6:7-13, Jesus calls His twelve apostles, emphasizing that it is Christ who appoints and commissions those who are to minister in His name. This reflects a divine calling rather than a human choice. Just as no man could appoint himself as high priest in the Old Testament, so neither can men choose to be pastors without being called by God. This divine calling ensures that those who serve as ministers are truly prepared and sent by the Lord to serve His people, demonstrating that Christ not only calls individuals but also equips them with the necessary power to serve effectively.
