make every effort to supplement your faith with virtue, and virtue with knowledge, and knowledge with self-control, and self-control with steadfastness, and steadfastness with godliness, and godliness with brotherly affection, and brotherly affection with love.
There is, I think, some confusion among some who are under the mistaken impression our faith shouldn’t involve any effort. While true, Jesus is the one who did the work of salvation, we are told to do our best to live rightly. We need to try hard to supplement our faith. Virtue is important. Knowing the truth and being able to think rightly is something we need to strive to do. What we do matters, we are able to control our reactions, and to remain steadfast in those actions and attitudes. Then we’ll be more like God, loving fellow Christians and caring for those around us. It’s not just a ticket to heaven, it’s a life committed to do good.
