“This chapter launches the thesis that will run throughout the rest of the book. That thesis is this: God has promised to save and keep his people through the means he has appointed and through no others; the ordinary means of grace are limited to the preached Word and the administered sacraments; God’s rationale for these means is made explicit in Scripture [emphasis original]. There are many other things that are essential for Christian growth: prayer, Bible study, service to others. However, these are not, properly speaking, means of grace but means of discipleship” (Michael Horton, A Better Way: Rediscovering the Drama of God-Centered Worship, 29).
