Continuing the thought from yesterday’s sermon of Paul’s presupposition that salvation will always produce transformation, Martyn Lloyd-Jones wrote this:
…regeneration is the profoundest change in the world, and that therefore we must always keep this in the forefront of our minds. A Christian is not just a man who has decided to be a little bit more moral than he was, or who has decided to join a church, or who has decided this or that, whatever it may be. What makes a man a Christian is that he has been born again, he has been given a new nature, he is a new creation, he is altogether different from what he was before.
This is the essence of saving faith — it makes a man different from an unbeliever. He is different in his person and that difference means that he is also different in his activity. Every part of his being is redeemed and every part of him is progressively sanctified into the likeness of Christ.
