Christians often think of the Gospel as the beginning of the Christian faith. As Tim Keller puts it, they see the gospel as the “first step” in a stairway of spiritual growth. But this is not a biblical picture of the gospel. Keller says that the gospel is “the hub of God’s wheel of truth.” Adding to this thought, J.D. Greear adds, “The gospel is not the diving board off of which we jump into a pool of Christianity, the gospel is the pool itself. That’s why growth in Christ is never going beyond the gospel, but going deeper into it.” 2
The gospel is the heart of Christianity. It is the center by which the Christian’s spiritual life flows into and out of Christ. We never grow away from this central reality. We never grow away from the cross. As Martin Luther said, spiritual progress is “always to begin again.” 3 The Christian should never grow weary of dancing around Jesus as the Lord of all things. The gospel is not the beginning of Christianity, the gospel is the hub by which everything else holds together.
