For the grace of God has appeared that offers salvation to all people. It teaches us to say “No” to ungodliness and worldly passions, and to live self-controlled, upright and godly lives in this present age, while we wait for the blessed hope—the appearing of the glory of our great God and Savior, Jesus Christ, who gave himself for us to redeem us from all wickedness and to purify for himself a people that are his very own, eager to do what is good.
We find again and again in scripture that God’s grace is key in our lives, in the lives of others. There are differences in teaching on this, as one might and should expect. There is what theologians call “common grace,” in which God pours down his blessings on all, in sunshine and rain, and provisions for life and more. This is not the grace described in this passage which brings salvation, according to scripture.
This is a big subject, but this post will touch mainly on one aspect of it, while addressing one common misunderstanding. God’s grace is alive and well in the world, and there is the light which enlightens every person (John 1). But the goodness and kindness of God is meant to lead people to repentance (Romans 2). There is no salvation apart from faith in Christ. It’s not just that somehow in an inexplicable, mysterious way that in the end all are saved through Christ. The NIV avoids this misunderstanding in the translation above, even if less literal. God’s grace is at work in all kinds of ways, but the special grace of salvation is always linked to repentance which means a turning from sin to God, and to faith, which means a trust in God and in God’s word, the message of the good news in Jesus.
Theologians also refer to “prevenient grace” which means the grace by which people receive the good news of the gospel for themselves by simple faith and trust in Jesus. Through Jesus’s death for our sins, and resurrection. We trust in what God has done for us through Jesus’s death, and receive forgiveness of our sins and new, eternal life.
So the grace which saves, to which the passage above refers, is not a cheap grace by which people get in with no change of life. Not at all. But at the same time grace is at work in spite of us, not because of us. That’s not to say that our efforts toward understanding and entering into this grace are a waste of time. Grace termed as prevenient by theologians might well include some of this striving, making every effort to enter into God’s rest (Hebrews 4). But also we have to remember that we still sin and have indwelling sin (1 John 1). And that is all the more true of those who have yet to cross over from death into life. They are sinners, period. Maybe Christians are both sinners and saints (Luther), depending on what you mean by that. God’s grace at work in people’s lives is in spite of so many things. God in his grace accepts us completely exactly where we’re at, but in God’s good grace, he certainly doesn’t leave us there.
Grace means we’re satisfied with nothing less than God’s salvation, which doesn’t mean only the forgiveness of sins, but also new life, a new way of living. By the Spirit in the love of God. Which means a changed life, a transformation both complete at conversion, and incomplete until Jesus returns (Philippians 1:6), meaning there is a process involved.
This grace gives us hope, and helps us to get out of God’s way, simply presenting the gospel, and trying to be responsive to God’s word. But this grace teaches us, teaches others. God’s full, unmerited, undeserved favor in helping us in ways beyond us, but in ways that indeed reach us in and through Jesus.
