Paul–The Old Testament, Luke, and the Old Covenant

“All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work.” (2 Timothy 3:16-17)
Paul affirms God’s active involvement in the writing of Scripture through his holy Spirit, including the Old Testament, an involvement so powerful and pervasive that what is written is the infallible and authoritative word of God.
