We fool ourselves into thinking we only harm ourselves when we give into addiction. I'm not sure what your habit is, but evil tends to radiate and multiply. Crooked people are in the business of perpetuating addictions. By consuming porn, we drive the sex trafficking industry. When we pay for cigarettes, tobacco farmers use our dollars to hire pre-teen prostitutes on the other side of the world. Even the most innocent-sounding addictions ruin relationships with the people we love the most.
So now we have given the pain in our hearts to God for healing. We have chosen to chase negative thoughts away with the truth of God's Word. Additionally, we chose healthier ways for us to fulfill our need for comfort, rest, adventure and escape as we draw nearer to God in our daily life. Now it's time to wrestle against the addiction itself.
Every time we don't give into an addiction, we are stronger for the next time we are tempted. In Matthew 4:1-11, Jesus was tempted by the devil in the desert. Satan tried over and over again until Jesus had resisted every temptation. Then the devil left Jesus alone. When the devil realizes we are not giving in, he too will leave us.
We are prideful creatures. Some part of us is still sure we can give up on our own even though we have failed so many times. Somehow our soul must try until it is broken. Then it will cry out for God in some mysterious uttering, and God will rescue all those who need and want His rescuing. He is our Deliverer! So try your very hardest over and over again until God shows up. This may include signing up for porn blockers, joining support groups like Celebrate Recovery, or something else. Just don't give up until you are delivered from your addiction. Earn your victor's crown. God is right beside you.
