2 Pet 2: 10-12
Bold and willful, they do not tremble as they blaspheme the glorious ones, whereas angels, though greater in might and power, do not pronounce a blasphemous judgment against them before the Lord. But these, like irrational animals, creatures of instinct, born to be caught and destroyed, blaspheming about matters of which they are ignorant…
Yet in like manner these people also…reject authority, and blaspheme the glorious ones. But when the archangel Michael, contending with the devil, was disputing about the body of Moses, he did not presume to pronounce a blasphemous judgment, but said, “The Lord rebuke you.” But these people blaspheme all that they do not understand, and they are destroyed by all that they, like unreasoning animals, understand instinctively.
Those who stood by said, “Would you revile God’s high priest?” And Paul said, “I did not know, brothers, that he was the high priest, for it is written, ‘You shall not speak evil of a ruler of your people.’”
The above verses are clear that we do not blaspheme the rulers both in the physical and spiritual realms.
Even though the devil had no jurisdiction over Michael, yet Michael would not revile him for he recognized the devil to be in a position of authority. (2 Cor 4:4).
It is one thing to criticize unjust policies of government but quite another to speak evil of the rulers. (Acts 23:5). It will be foolish for naive pastors to join the false teachers (being described above as irrational animals) in speaking evil of the devil or the government leaders (such as President Trump of USA and President Xi of China) and attributing the blame to them for the current hard times.
We must accept nothing happen outside God’s sovereign will. It is judgment and training for the wicked and the faithful respectively. God has warned repeatedly in Scripture of coming hard times and of course, ONLY the faithful listen, stay watchful, prepare and endure.
This is worth noting from the above Scriptural references that the false teachers, though they are agents of the devil, can even blaspheme the devil. This reveals that evil can go to that extent of deception.
