Once you were alienated from God and were enemies in your minds because of your evil behavior. 22 But now he has reconciled you by Christ's physical body through death to present you holy in his sight, without blemish and free from accusation-- 23 if you continue in your faith, established and firm, not moved from the hope held out in the gospel. This is the gospel that you heard and that has been proclaimed to every creature under heaven, and of which I, Paul, have become a servant.
"Enemies" and "evil behavior" strike me. I just preached a sermon on total depravity, and while people will agree that we are unable to save ourselves, no one really wants to call themselves evil or even describe their behavior as evil. That's a harsh word. Someone even told me, you don't think that I'm incapable of doing any good at all do you? I can't be completely evil? Unfortunately for us that is the case. Without God, without Christ, we are non posse non peccare or "I cannot not sin." This isn't just the case of us not being able to save ourselves, but our natures are evil and thus our behavior is evil and we are enemies of God. Enemies, like Nazi's vs. Allies enemies, only we're the Nazi's. I know this sounds harsh but it's scriptural truth. It's only when we receive a new nature, a new spirit, that we become posse non peccare, or "Possible to not sin." We are able to do good because of Christ, after all apart from him "you can do nothing." This is why the hope held out in the gospel (v.23) is such good news. This is why we become servants of the gospel, because we have been ransomed from sin, death, and total depravity.
