Ephesians 1:1

(1:1) An "apostle" is one with authority and a commission--One who operates and lives within the protection and directives of the one who sent him out. It is in this very sense that Paul declares himself to be "an apostle of Christ Jesus" with singleness of purpose. He belongs totally and solely to his Lord. In order that we not mistake his commission, he plainly states that he was conscripted into service "by the will of God". You will recall that on the road to Damascus, Paul was struck down by the brilliant presence of the ascended Jesus. There he was confronted with the gospel of His saving work and he was drawn directly into serving Him.
