Know your Enemy know Sin!! not to give glory to the devil, but to keep your self free from sin! To take a little of your time to study what Sin is that way you can keep your self free from falling into its vice and power.
I use a book called " Manual for Conquering Deadly Sin" it covers the 7 Deadly Sins. How to spot and know its vice so you dont fall into them or if you do fall into them how to conquer them and get back on your feet.
The path to holyness and virtue takes work, Faith with out works is dead. It takes a daily pratice, its like the famous saying goes pratice makes perfect, it sure does! we all heal One day at a time. If we want to go somewere we must start by taken steps and moving in the direction we want to go.
Fighting sin is a daily work out and pratice walking thy narrow path that Jesus talks about. Its a walk that we take going in the right direction. Spend some time in daily meditation that way you can practice good habbits.
