In this short book, Paul is going to talk about faith, the knowledge of truth and how that leads to godliness. We see that Paul understands himself to be a slave of God - not belonging to himself, bought with a price that is the blood of Jesus. And like Paul, we also do not belong to ourselves but to God. We have been chosen by God for his purpose. Our salvation is completely dependent upon God and as we are freed from sin we are enslaved to God for righteousness.
