But Jesus said unto them
Not by granting them what they desired, but by observing their ignorance to them;
ye know not what ye ask:
for sometimes good men are ignorant petitioners at the throne of grace; they are under the influence of their own spirits, and not the Spirit of God; they are prompted to ask things from a selfish principle, and not with a view to the glory of God, and their own spiritual welfare, and that of others: and indeed, the best of saints know not what they should pray for as they ought; and always stand in need of the help, assistance, and intercession of the Spirit of God; who is a Spirit of grace and supplication, and searches the deep things of God, and knows his mind and will, and what is suitable and convenient for his people; and whenever they pray without him, there is much darkness and ignorance in them, and in their petitions. In particular, these disciples knew not what they were asking for; they had no true notion of Christ's kingdom and glory, they were asking the chief places in; they were dreaming of worldly glory and grandeur, in which they imagined the kingdom of the Messiah would quickly appear: whereas his kingdom, in the present state of things, is not of this world, but of a spiritual nature; namely, the Gospel dispensation, which lies in the ministration of his word and ordinances, and in the distribution of his gifts and grace; and his kingdom and glory in the world to come, are things which eye has not seen, nor ear heard: they talked of things which would never be, either in Christ's kingdom, in earth or in heaven; fancying there would be posts of honour and profit, which some would be advanced to in it, signified by sitting at his right hand and left; whereas in the Gospel church state, the apostles, governors, and officers of the church were alike, and had no superiority over one another, but were all brethren, having one master, Christ; and the members of the churches are of the same body, and members one of another; and in the ultimate glory, there will be no degrees, but all the saints will share the same happiness:
can ye drink of the cup that I drink of, and be baptized
baptism that I am baptized with?
Which Christ speaks of in the present time, partly because his sorrows and sufferings were already begun: he had already been drinking of the cup of sorrows, being a man of sorrows and acquainted with griefs, all his days; and he was wading in the waters of affliction, though as yet they were not come into his soul, and he as it were immersed in them; he was not yet baptized with the bloody baptism he came into this world for, and he was desirous of, ( Luke 12:50 ) , and partly because of the certainty of these things, the cup was not to pass from him, and the baptism of his sufferings was to be surely accomplished; (See Gill on Matthew 20:22).
