The glorious good news of the gospel is that the sin-devastated relationship between lost sinners and the holy God can be restored. That at first glance seems impossible. God’s perfect, infinite, righteous justice demands the punishment of all who violate His law. Standing before the bar of His justice are helpless, guilty sinners, unable either to satisfy God or to change their condition. But through God’s plan of reconciliation all the hostility, animosity, and alienation separating the Holy One and sinners vanishes, and those who were once His enemies become His friends. The high calling and noble privilege of preaching this message of reconciliation is the most important duty in the world, since it deals with eternal destinations.
