It is true and well to note, that evil is introduced by intermediaries. God did not
directly afflict Job. Satan was His instrument. Yet Job was not deceived. Even
the dim light in which he lived was sufficient to lead him back to the One Who
is the primal Cause of all. He did not say "Shall we receive good at the hand of
God, and shall we not receive evil at the hand of Satan?" There would have
been much truth in that. He received evil at the hand of God (Job
2:10). Let us
learn the lesson Job knew so well and boldly say, "The Lord gave and the Lord
hath taken away; blessed be the name of the Lord!" Is this a sin? Is this
charging God foolishly? "In all this," we read, "Job sinned not, nor charged God
foolishly" (Job
1:21,22).
