There is ultimately no justification for a private piety that doesn’t work out in actual mission, just as there is no justification for people who use their activism in the social, cultural, or political sphere as a screen to prevent them from facing the challenges within their own lives – the challenge, that is of God’s kingdom, of Jesus’s lordship, and of the Spirit’s empowering. If the gospel is not transforming you, how do you know it will transform anything else?
