This is a study of Paul's letters to the Galatians, Ephesians, Philippians, and Colossians. From personal experience, Paul knew what it was like to be the persecutor (as the Pharisee Saul), and the persecuted (as the Apostle Paul.) Having been taught at the feet of the Lord Jesus Christ, Paul explained many doctrines of the Christian faith and gave many practical encouragements in these four letters.Paul explained the Lord's solutions to each of the problems facing these four named peoples. The problems they faced may have been specific to Paul's day and age, but all saints since then have had to deal with similar problems. Paul's words are as valuable today, almost 2000 years later, as they were in the 1st Century A.D. when freshly written.
