In Galatians Chapter 1, the Apostle Paul is correcting teachings from others claiming that Judaism and all the law still needed to be followed along with being a Christian. His apostleship was being questioned and he reminds the church in verse 4 that this word did not come through man. In Galatians 1:8 Paul warns the church that if anyone preached any other gospel, even an angel from heaven, they should be accursed. Despite this warning, there are several religions today that claim to have gotten their teachings from angels including Mormonism and Muslims.
The history of Paul, including his conversion on the road to Damascus in Acts 9, his background as a scholar and persecutor of Christians in Acts 7 and 8 is discussed in this sermon. God used Paul’s background as a scholar to show how Christ was in the Scriptures.
In Galatians 1:10 it reminds us not to please men, but Christ and in Acts 22:3 Paul reminds us that with God all things are possible.
