God’s Best Gift: Being Eternally Enthralled with God
This is crucial to see. Many people seem to embrace the good news without embracing God. There is no sure evidence that we have a new heart just because we want to escape hell. That’s a perfectly natural desire, not a supernatural one. It doesn’t take a new heart to want the psychological relief of forgiveness, or the removal of God’s wrath, or the inheritance of God’s world. All these things are understandable without any spiritual change. You don’t need to be born again to want these things. The devils want them.
It is not wrong to want them. Indeed it is folly not to. But the evidence that we have been changed is that we want these things because they bring us to the enjoyment of God. This is the greatest thing Christ died for. This is the greatest good in the good news. Why is that? Because we were made to experience full and lasting happiness from seeing and savoring the glory of God. If our best joy comes from something less, we are idolaters and God is dishonored. He created us in such a way that his glory is displayed through our joy in it. The gospel of Christ is the good news that at the cost of his Son’s life, God has done everything necessary to enthrall us with what will make us eternally and ever-increasingly happy–namely, himself.
