And so it was, after the LORD had spoken these words to Job, that the LORD said to Eliphaz the Temanite, “My wrath is aroused against you and your two friends, for you have not spoken of Me what is right, as My servant Job has. Now therefore, take for yourselves seven bulls and seven rams, go to My servant Job, and offer up for yourselves a burnt offering; and My servant Job shall pray for you. For I will accept him, lest I deal with you according to your folly; because you have not spoken of Me what is right, as My servant Job has.”
Interestingly, Job had really railed against God on several occasions. But God’s “wrath [was] aroused” by those who spoke wrongly of Him. This is what God considered foolishness (and demanded repentance from), not the rantings of a confused man.
Certainly, we should always strive to be respectful of God. But when we blow it, He’s big enough to handle it, and He doesn’t frown on that nearly as much (if at all) as He does on those who are full of respect, but speak wrongly of Him.
