To be effective in ministry, the gospel must be central in everything we do: every sermon we preach, every devotional we write, all of our small group curriculum, and in every aspect of the life of our churches. If the gospel is not central, our churches will be built on sand and will eventually collapse into a religious relic or a glorified version of a self-help pep rally. If we’re not preaching the gospel, we are preaching a cubic zirconia version of the divine diamond of the universe- the gospel.
