Is Sanctification Mongeristic or Synergistic?

In this article, Kevin DeYoung addresses question of whether sanctification is a monergistic or synergistic work – original source here:

Recently, in a leadership training class at our church, a spirited discussion broke out on whether sanctification is monergistic or synergisitic. No, this is not what every class is like at University Reformed Church. But this one was. I wasn’t there, but I was told the discussion was energetic, intelligent, and respectful. I’m glad to serve at a church where people know and care about this level of theological precision.

The terms monergism and synergism refer to the working of God in regeneration. Monergism teaches that we are born again by only one working (mono is Greek for “one,” erg is from the Greek word for “work”). Synergism teaches that we are born again by human cooperation with the grace of God (the syn prefix means “with” in Greek). The Protestant Reformers strongly opposed all synergistic understandings of the new birth. They believed that given the spiritual deadness and moral inability of man, our regeneration is owing entirely to the sovereign work of God. We do not cooperate and we do not contribute to our being born again. Three cheers for monergism.   Continue at John Samson
