John says of Jesus:
Mat 3:12 Whose fan is in his hand, and he will throughly purge his floor, and gather his wheat into the garner; but he will burn up the chaff with unquenchable fire.
While Jesus says of Satan:
Luk 22:31 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:
Did Jesus and Satan do the same work of God by sifting the saints?
