The reason so many in the nations remain in darkness is that so many in the church live as light salesmen. We preach a gospel that makes promises to people of light, if only they will pay a price. But there is no power in preaching a gospel that points people to their behaviour as their hope of light. There is no power in a gospel that points people to themselves! There is no power of the Spirit in such a man-centred gospel to bring people out of darkness because we have not been given God’s Spirit that we would be promisers of the light, but that we would be the light.
