Read Robert Mulholland's quote below. How does what he says here fit with your own experience of transformation?
If, indeed, the work of God's formation in us is the process of conforming us to the image of Christ, obviously it's going to take place at the points where we are not yet conformed to that image. This means that one of the first dynamics of holistic spiritual formation will be confrontation. Through some channel—the Scripture, worship, a word of proclamation, the agency of a brother or sister in Christ, even the agency of an unbeliever—the Spirit of God may probe some area in which we are not conformed to the image of Christ. That probing will probably always be confrontational, and it will always be a challenge and a call to us in our brokenness to come out of the brokenness into wholeness in Christ. But it will also be a costly call, because that brokenness is who we are. (Invitation to a Journey, p.37)
