Galatians 1:1-2… 1 Paul, an apostle (not sent from men nor through the agency of man, but through Jesus Christ and God the Father, who raised Him from the dead),
Paul said that he was an apostle—sent on a mission by God and Jesus with the authority of the senders. Some people thought that he was not a genuine apostle like the others whose calls directly from Jesus. Here Paul said his calling to be an apostle did come from Jesus and God the Father; it came on the Damascus Road and his training directly from Jesus in Arabia A. Paul was absolutely certain of the resurrection of Jesus, He had seen Jesus, and only a living Savior can give repentant sinners new life. Therefore Paul was insistent about the necessity of the resurrection for salvation. B Paul was establishing his authority to write to the churches about matters of faith.
2 and all the brethren who are with me, To the churches of Galatia:
In designating the sender of the letter, Paul included all the brothers–members of God’s family traveling and serving with him in the ministry. Paul addressed his letter to all the churches in the Roman province of Galatia and to readers down through the centuries. Paul sometimes complimented churches in the first part of his letters C, but maybe because the Christian congregations in Galatia were allowing false teachers to influence them, he had no compliments for them. D
Paul was an apostle through Jesus and God the Father!
