Fundamentally, the survival of the church in a post-Christian age comes down to a promise and a command given us in Scripture, an indicative and an imperative. First, we must remember that Jesus promised, “I will build my church, and the gates of hell shall not prevail against it” (Matt 16:18).
Next, we must remember that we have been commissioned to “make disciples of all nations” (Matt 28:18-20). We need to remember both of these words from Scripture in order to evangelize faithfully and maintain our evangelical identity.
As we evangelize we must keep the gospel and the person of Christ central and we must unashamedly and winsomely teach our evangelical commitments. We must talk about God’s holiness and righteousness, we must talk about sin, and we must talk about our need of a Savior. The core of the good news is the person and work of Jesus Christ. He is the one we must talk about most of all — and without fail.
