The enemy is trying to plague you with condemnation but Jesus gives us conviction. I used to be in the same situation you were and I realized that I was allowing my sin to make me run away from Jesus because I was ashamed. but then I remembered that Jesus died on the cross for us to be able to be forgiven and so instead of running away from him, I ran closer to him and now I don’t struggle with lust anymore, and I now understand that when I sin that I have forgiveness available to me at any place anytime. so I just pray that you will run closer to God instead of running further away and I rebuke that spirit of condemnation and I speak that right now, In the name of Jesus you have a spirit of peace and forgiveness in Jesus name amen.
