The Apostle Paul sent Timothy to support the work of the gospel in Corinth because he was faithful in the Lord. Timothy was also sent to Philippi – Philippians 2:19-22 But I trust in the Lord Jesus to send Timotheus shortly unto you, that I also may be of good comfort, when I know your state. 20 For I have no man likeminded, who will naturally care for your state. 21 For all seek their own, not the things which are Jesus Christ’s. 22 But ye know the proof of him, that, as a son with the father, he hath served with me in the gospel. He was a convert in the Apostle Paul’s ministry.
