I would start with what is going on now. There’s a lot of crazy stuff going on. The enemy of your soul will rush in to show you the long list of your faults. Don’t listen to him. Ask God where he wants you to start. The first time I realized God was real and actually knew who I was, I rushed out and bought a King James Version of the Bible. It might has well been in a foreign language. I got pissed and threw it and fussed at him. The next day, I picked it up and read it clear as day. We have a lot of programming he has to undo, and that is different for everyone. Relax a bit.
When I get overwhelmed I take that pile and dump it as his feet, so to speak. It’s my sacrifice. He wants our fears and doubts, not our good deeds. He wants relationship not a strict, cold formality. That is what “the church” teaches. He wants to live in your heart and show you awesome things, that you also like.
Don’t worry about the sin you see. Ask him what he wants to show you about it instead. All the things he’s cleaned up in me came from healing, not trying. One day you wake up and just realize that what you were struggling with is gone…. or not. That’s okay too as long as you don’t give up on that relationship. We are in a world of broken people. Perfect people are not easy to relate to. I can’t stand being around people who pretend to be perfect. I don’t hate them, but I do hate their behavior. He did that for me. I used to hate them. Now I don’t…. Bitterness almost destroyed me. Now it’s gone…. That is what this world needs. Healed people that know they’re loved, even though they’re still a mess. Those are the ones that will love others.
