it sure does begin in our minds.and not only for addictions. you can also include insecurities, low self esteem and trust issues . thats a big one it affeced my relationship with the most beautiful woman in the world.
You are so damaged that even if you feel like it is from God, you get scared and run. Your fear is bigger than your faith. It's a shame because you are amazing and deserve a God centered relationship, not a Satan founded one.
