Last week we asked the question: why is it so important to get the gospel right? Jono mentioned that it is important to get right because if we spoil the gospel, our eternity and the honour of Jesus are at stake. Since it is so critical to get the gospel right, we should also ask the question: how do we know the gospel we believe is authoritative?
This week, we will answer this question by looking at how Paul establishes his authority to the Galatian church.
