This expression is used in Mt 3:11. The copulative kai requires that the baptism "in the Holy Ghost and in fire," should be regarded as one and the same thing. It does violence to the construction, therefore, to make this statement refer to the fire Of judgment. The difficulty has always been in associating fire with the person of the Holy Ghost. But in the connection of fire with the work or influence of the Holy Ghost the difficulty disappears. The thought of John is that the Saviour would give them the Divine Sanctifier as purifying water to wash away their sins and as a refining fire to consume their dross; to kindle in their hearts the holy flame of Divine love and zeal; to illuminate their souls with heavenly wisdom. The statement, therefore, in this verse indicates the manner in which Christ will admit them to discipleship and prepare them for His service.
