How does the Gospel reveal our true hearts?

The Gospel serves as a mirror to our souls, revealing whether we genuinely trust in Christ or are relying on our own righteousness. For instance, the Pharisees, who appeared zealous for the law, were confronted by Christ, exposing their hearts' enmity against Him. The message of grace, which declares Christ as our only righteousness, makes clear who is truly seeking Him as Savior versus who is simply adhering to a religious routine. It's through the proclamation of the Gospel that one’s heart is laid bare, demonstrating whether they are seeking earthly treasures or recognizing Christ as their greatest treasure.
