My problem with some of these saying that God sent, or God harden their hearts or blinded their eyes, puts God as the cause of their evil or sin....How does that comport with the nature of God? Would not God then be the cause of their sin or evil.
Read about what God did to Pharaoh.
God is not the author of sin, but He exists outside of time. He knows who will and who won’t take His invitation to join Him in Eternity.
Those whom He knows will forever reject Him are used of Him to accomplish His purposes, which usually includes their destruction in this plane as well as in Eternity.
Note my comment above.
