Why would a demon perform an act which appears to accrue to the greater glory of God?
If they do, I would think deception would be the reason. When the beast and false prophet are on the world scene, I suspect there will be a whole lot of deceiving going on out there.
Good question!
Why WOULD the Jehovah Witness group give glory to GOD to attract members?
Why WOULD Mormons go door to door, all over the world, to give PRAISE to Jesus?
Why WOULD Muslims approve so much of what Jesus did on earth?
“The end justifies the means”
“appears”
If Satan has to give a little Glory to God for your soul that would be a good trade don’t you think?
If Satan performs a miracle and you attribute that to a Saint and not the real miracle worker God then you have gave Honor, Respect, and Glory to Satan.
2 Corinthians 11:13-15 New Revised Standard Version Catholic Edition (NRSVCE)
13 For such boasters are false apostles, deceitful workers, disguising themselves as apostles of Christ. 14 And no wonder! Even Satan disguises himself as an angel of light. 15 So it is not strange if his ministers also disguise themselves as ministers of righteousness. Their end will match their deeds.
1 John 4:1 New Revised Standard Version Catholic Edition (NRSVCE)
4 Beloved, do not believe every spirit, but test the spirits to see whether they are from God; for many false prophets have gone out into the world.
