Previously title Striving Against Satan (Bryntirion Press). If you are a true believer Satan hates you. This sobering thought should make us reflect seriously upon our enemy. Dr Joel Beeke does this systematically. Thus we have studies on ‘Knowing the Enemy’ – his history and personality, weaknesses, strategies, and (crucially) his defeat. When many do not believe in the devil’s existence, and laugh at the suggestion, Christians need to be aware, warned, and encouraged.
