9:54 {12} And when his disciples James and John saw [this], they said, Lord, wilt thou that we command fire to come down from heaven, and consume them, even as Elias did?
(12) We must take heed of zeal and fond imitation which is not moderated, even in good causes, that whatever we do, we do it to God's glory, and the profit of our neighbour.
9:54 Wilt thou that we command fire? These gentle apostles were filled with wrath at the insult to the Master. Their zeal for the Lord led them into a sanguinary feeling that was sinful. Thus, often, religious zeal has led men to sinful acts and a persecuting spirit.
As Elijah did? See 2Ki 1:9-12.
9:54 As Elisha did - At or near this very place, which might put it into the minds of the apostles to make the motion now, rather than at any other time or place, where Christ had received the like affront.
9:51-56 The disciples did not consider that the conduct of the Samaritans was rather the effect of national prejudices and bigotry, than of enmity to the word and worship of God; and through they refused to receive Christ and his disciples, they did not ill use or injure them, so that the case was widely different from that of Ahaziah and Elijah. Nor were they aware that the gospel dispensation was to be marked by miracles of mercy. But above all, they were ignorant of the prevailing motives of their own hearts, which were pride and carnal ambition. Of this our Lord warned them. It is easy for us to say, Come, see our zeal for the Lord! and to think we are very faithful in his cause, when we are seeking our own objects, and even doing harm instead of good to others.
