Paul is very disappointed to see the church in Galatia moving away from the Christian gospel. In his letter to Galatia, he skips the thanksgiving which is generally included after the salutation in letters during this time. Paul might have skipped this part of the letter because he wanted to get into the more meaty part of his letter. It could be that Paul had nothing to thank the Galatians for. However, I think the former is more likely and Paul was simply disappointed in the Galatians very much. Paul clearly has a good relationship with the Galatians in order to write them, critique them, and challenge them in their faith. Paul humbles himself before God, emphasizing the fact that the Gospel comes from a divine source and is by no means derived from a human source. This is very important in his letter to the Galatians as it gives them a much stronger reason to follow the Gospel. Also, the emphasis on the divine make Paul look humbled to the Galatians. It gives him authority to speak with them as he is a mere human just like them. Galatia has begun to turn its back on the message of the Gospel. In the beginning of his letter to Galatia, Paul is firm but encouraging as well. He wants Galatia to get back on track and he encourages them to do so. There is definitely a hint of disappointment in his voice though. In Galatians 1:13-17, Paul uses his story to help illustrate why the Galatians should continue in the Gospel. Paul details how he persecuted Christians and then all of sudden God revealed himself to Paul. He claims that his life changed after that point and it is suggestive that Paul wants that for the Galatians. Galatians 1:23-24 also illustrates this idea. Paul was a walking testament to Christians. They saw how much he had changed after deciding to follow God that they were amazed and moved to glorify God as well. Through his letter to the Galatians, it is clear that Paul wants the Galatians to change their ways and glorify God.
