An excellent piece by professor Witherington on the Satan.
C.S. Lewis once said it is perhaps the greatest trick or smoke screen or deception of Satan to convince people that they are too wise to believe in him. But at the same time, it is a mistake to give him too much credit as well. There is a balance between the extremes reflected in the NT, and this is in part because all of the writers of the NT believe they live in ‘this present evil age’ which, now that the Kingdom is breaking in, is passing away. Satan, after the death and resurrection of Jesus is fighting a rear guard action, for he has already lost the battle of D Day, and V-E Day is coming when Christ returns.
