Saving faith is the cry of a new creature in Christ. And the newness of the new creature is that it has a new taste. What was once distasteful or bland is now craved. Christ Himself has become a Treasure Chest of holy joy. The tree of faith grows only in the heart that craves the supreme gift that Christ died to give: not health, not wealth, not prestige—but God!18 Test yourself here. There are many professing Christians who delight in God’s gifts, but not God. Would you want to go to heaven if God were not there, only His gifts?
