Satan certainly has power, but that is clearly not absolute even over earthly matters. Did he just happen to take Election Day off in 2016?
I doubt he took off election day, but I think more people said NO that day than YES. Actually, more people said YES than NO, but the genius behind the electoral college put Trump into office.
And, no, of course Satan does not have absolute power on the earth, only what God allows him to do. Do you dispute that Satan can exercise some power?
You must take in account the resurrection. Satan didn’t tempt Jesus with an empty test. Those kingdoms and their glory we’re his through Adam’s fall. Now the kingdom has come and the church has been given the authority to drive back the darkness and destroy the work of God’s enemy.
