One of the most reassuring truths about our Christian life is that what Christ did on the cross was a completed work (John 19:30; cf. John 17:4). Now, we have everything we need for life and godliness in Him (2 Pet. 1:3). In verses 11-15, Paul tells us what Christ has completed for us so that we can stand firm against the false teachers who would try to rob us of our sufficiency in Christ.
