A man set on fire is an apostle of his age. And the only one who can kindle the spark of light and fire on the hearth where it has died down is He who has revealed Himself as the God of fire, our Lord Jesus Christ. ‘Our God is a consuming fire’. . . . Tell me, is your ministry a burning and shining light, or a smoking wick, slowly dying out to ashes? . . . It is a strange custom that we should supply a minister with a glass of water; if only we could supply him with a bonfire in the pulpit, a spiritual bonfire. We need the dynamic of a flaming ministry that will set the Church on fire.
