“Though clearly distinguished, sanctification is not separated from the new birth and justification but utterly dependent on both. Too often, we assume that the gospel of free salvation in Jesus Christ, apart from our own efforts, is good news for unbelievers but that believers no longer need it. They “got saved,” after all, and now what they need are exhortations to live for Jesus. Sanctification, then, becomes unhinged from justification and the new birth, so that we easily confuse our performance in the Christian life with the gospel. Instead, sanctification must be seen as the outworking of our justification and union with Christ. Obedience is often difficult and demanding – it doesn’t just happen to us but is something that we work out with fear and trembling. As essential as this new obedience is to Christian identity, if our acceptance before God were founded on it there could be absolutely no hope” (Michael Horton, A Better Way: Rediscovering the Drama of God-Centered Worship, 71).
