No one can receive anything except what has been given from heaven.
“Holy Gospel of Jesus Christ according to Saint John 03/22-30: “After this Jesus and his disciples went into the Judean countryside, and he spent some time there with them and baptized. John also was baptizing at Aenon near Salim because water was abundant there; and people kept coming and were being baptized John, of course, had not yet been thrown into prison. Now a discussion about purification arose between John’s disciples and a Jew. They came to John and said to him, ‘Rabbi, the one who was with you across the Jordan, to whom you testified, here he is baptizing, and all are going to him.’ John answered, ‘No one can receive anything except what has been given from heaven. You yourselves are my witnesses that I said, “I am not the Messiah, but I have been sent ahead of him.” He who has the bride is the bridegroom. The friend of the bridegroom, who stands and hears him, rejoices greatly at the bridegroom’s voice. For this reason my joy has been fulfilled. He must increase, but I must decrease.”
Satan disguises himself as an angel of light. So it is not strange if his ministers also disguise themselves as ministers of righteousness
“Second Letter to the Corinthians 11/07-15: “Did I commit a sin by humbling myself so that you might be exalted, because I proclaimed God’s good news to you free of charge? I robbed other churches by accepting support from them in order to serve you. And when I was with you and was in need, I did not burden anyone, for my needs were supplied by the friends who came from Macedonia. So I refrained and will continue to refrain from burdening you in any way. As the truth of Christ is in me, this boast of mine will not be silenced in the regions of Achaia. And why? Because I do not love you? God knows I do! And what I do I will also continue to do, in order to deny an opportunity to those who want an opportunity to be recognized as our equals in what they boast about. For such boasters are false apostles, deceitful workers, disguising themselves as apostles of Christ. And no wonder! Even Satan disguises himself as an angel of light. So it is not strange if his ministers also disguise themselves as ministers of righteousness. Their end will match their deeds.”
