Unbelievers can perform miracles in Jesus's Name

Matthew 7:21-23 (New American Standard Bible)
Not everyone who says to Me, 'Lord, Lord,' will enter the kingdom of heaven, but he who does the will of My Father who is in heaven will enter.
Many will say to Me on that day, 'Lord, Lord, did we not prophesy in Your name, and in Your name cast out demons, and in Your name perform many miracles?'
And then I will declare to them, 'I never knew you; DEPART FROM ME, YOU WHO PRACTICE LAWLESSNESS.'

Numbers 24:2 (New American Standard Bible)
And Balaam lifted up his eyes and saw Israel camping tribe by tribe ; and the Spirit of God came upon him.

Many miracles were performed by money loving pastors. These miracles are performed in Jesus's Name. But on the day of judgement, Jesus will deny them. We already have an example in the Old Testament, where the prophet Balaam, who is rejected by God, although he is a true prophet who prophesied in God's name.

Balaam is a warning to all the money loving miracle working pastors, who "loved the wages of unrighteousness" (2 Peter 2:15-16).
