"Christian growth does not happen by working hard to get something you don’t have. Rather, Christian growth happens by working hard to daily swim in the reality of what you do have. Believing again and again the gospel of God’s free, justifying grace everyday is the hard work we’re called to.From: Tullian Tchividjian - Rethinking Spiritual Growth
This means that real change happens only as we continuously rediscover the gospel. The progress of the Christian life is “not our movement toward the goal; it’s the movement of the goal on us.” Sanctification involves God’s attack on our unbelief—our self-centered refusal to believe that God’s approval of us in Christ is full and final. It happens as we daily receive and rest in our unconditional justification. As G. C. Berkouwer said, “The heart of sanctification is the life which feeds on justification.”"
