The catechism answer tells us two things about the glorious future that the gospel assures us is coming.
First, we are going to enjoy God forever. Because God is triune within himself, Father, Son, and Holy Spirit have been glorifying each other, delighting in each other, adoring each other, loving each other. Therefore, God within himself has infinite joy. And we were created to share in that joy. We were created to glorify him and to participate in that glory and joy. But none of us, even the strongest Christians today, have ever experienced what that joy is—perfect, cosmic, infinite, endlessly growing—because all of us worship and adore other things. Someday we will be freed from sin, and then we will know and experience that glory and joy. We will enjoy him forever.
Second, we will enjoy him forever in the new city, in the New Jerusalem, in the new heavens and new earth. We will experience this cosmic joy not in a purely immaterial condition. But, rather, we will be in a restored material creation. We will have resurrection bodies like Jesus’s body—physical bodies. And what that means is, as Christianity envisions, the body and the soul, the physical and the spiritual, are together in perfect harmony forever. No other religion envisions that. We will not float about as disembodied spirits, but we will dance. We will march. We will hug. We will be embraced. We will eat, and we will drink in the kingdom of God. It means all of our deepest longings will be fulfilled. All of our greatest sorrows will be swallowed up.
What could be better than that? And that’s what we’re in for. Nothing less.
