John Calvin Commentary Ezekiel 9:11

"And behold, the man clothed in linen, who had the inkhorn by his side, reported the matter, saying, I have done as thou hast commanded me." — Ezekiel 9:11 (ASV)

This sentence confirms what I said yesterday about God’s fatherly concern for the faithful. For the Prophet taught that, before God would permit the Chaldeans to destroy the city, an angel was sent beforehand to aid the elect and thus to set himself against the violence of the enemies. Through this, as we have said, it is shown to us as if in a mirror that God maintains this order in his judgments: his fatherly love for the faithful always precedes them, so that he does not permit anything to happen to them except what contributes to their safety.

For this reason, the angel now says, that he had done as he was commanded. Undoubtedly, the angel's obedience is reported to us because it corresponds to the will of God. Therefore, we gather that the safety of the faithful is always precious to God, and so they will always be safe and secure, even when it seems heaven and earth are collapsing together. This, then, is the explanation.
