“There is no greater message to be heard than that which we call the Gospel. But as important as that is, it is often given to massive distortions or over simplifications. People think they’re preaching the Gospel to you when they tell you, ‘you can have a purpose to your life’, or that ‘you can have meaning to your life’, or that ‘you can have a personal relationship with Jesus.’ All of those things are true, and they’re all important, but they don’t get to the heart of the Gospel.
The great misconception in our day is this: that God isn’t concerned to protect His own integrity. He’s a kind of wishy-washy deity, who just waves a wand of forgiveness over everybody. No. For God to forgive you is a very costly matter. It cost the sacrifice of His own Son. So valuable was that sacrifice that God pronounced it valuable by raising Him from the dead – so that Christ died for us, He was raised for our justification. So the Gospel is something objective. It is the message of who Jesus is and what He did. And it also has a subjective dimension. How are the benefits of Jesus subjectively appropriated to us? How do I get it? The Bible makes it clear that we are justified not by our works, not by our efforts, not by our deeds, but by faith – and by faith alone. The only way you can receive the benefit of Christ’s life and death is by putting your trust in Him – and in Him alone. You do that, you’re declared just by God, you’re adopted into His family, you’re forgiven of all of your sins, and you have begun your pilgrimage for eternity.”
