The illustration of differences by looking at the two sons of Abraham.  Review of Genesis 16:1-6 for the analogy of the two sons.  Paul then illustrates two theological paths, thus not mixing the Law with the Gospel.

Paul is teaching the Galatians to leave works righteousness, reminding them that their relationship with the Law changed they embraced Christ.

Galatians had embraced the Judaizers' teaching.  Paul explained that that the Law was the equivalent to the elementary teachings of Paganism.  The Law was not a bad thing but showed us the need for a Savior.

We are adopted as "Sons of God", where there is no distinction between male or female, classes, Jew or Gentile. 

Gen. 12:1-3 - Abrahamic Covenant.  The Abrahamic Covenant wasn't fulfilled through the Law but through Christ.  The Law doesn't affect salvation but shows us that we need a Savior.

The Law is to show us that we need a Savior.  With Jesus' death & resurrection, we are now under grace.  We do not earn our salvation by works.

Paul confronts Peter regarding hypocritical behavior.

Paul speaks with the leaders of the early church.  They recognize that Paul was called to minister to the Gentiles.  Even though 2 different groups of people being ministered to, the Gospel is still the same.

Paul starts by explaining his conversation, his background and then God's trajectory for Paul's ministry.

Paul starts his letter to the Galatians with a deep greeting that is more than just "hello".
