In the previous sermon we talked about how we guard ourselves against false teachings, and in 9-15 Paul turns our attention to the one and only true teaching—the gospel of Jesus Christ. Every false teaching some way or another says/implies Christ work and His salvation is incomplete. But Paul shows us in verses 9-15 that we have complete salvation in Jesus Christ by transforming us, giving us complete forgiveness, and complete victory.
I hope this message blesses you!!
