Can you fight an already won battle? What if I say I am going to fight and liberate India from the British rule? Do I make any sense? The fight is already over and India is already free from British rule. All I need to do is to enjoy my freedom and protect my already won freedom. Fighting the actual war for freedom is completely different from protecting your already won territory.
But sadly, that’s what we do most of the time spiritually. We try to fight the war against the devil, which is already won. Jesus has disarmed the powers and authorities and He has made a public spectacle of them, triumphing over them by the cross. (Col 2: 15). So who are trying to disarm? The devil is a liar. The battle already won. You just have to enjoy your freedom and protect your freedom. Don’t try to fight a battle that has already been won by Jesus on the cross. Just don’t give the devil a foothold.
