"Ye know not what manner of spirit ye are of" (Luke 9:55). Satan tempts saints to unholy wrath, and they do not know until, as here, He tells them where they got the coal that so heated them.

It is great presumption to send our passions upon God's errands, as it is also to palliate them with God's name. Zeal, dropped in love, is good; without it, good for nothing; for it devours all it touches. We will not overshoot the mark about others if first we have been with God about ourselves.
