If people decides to live without God, I don't care.
And this is why you failed as a Christian. You never cared whether or not other people "had, are or will" live with God. You had a conflict within yourself and were just trying to convinced yourself that you "had, are, or will be living with God. You were explaining about God to others on the outside to convinced your inner self, not caring whether they will learn something about God or not.
At least it's a start. You have finally confessed and starting to move away from the shadow, leaving the stage of denial. The next step will be for you to keep following the light and walk farther away from the shadow. Hopefully you will not turn back towards the shadow back into denial. The shadow will at times try to pull you back to the easy path leading you back to the shadow. The path in front of you will be a difficult road to walk on, and at times you will feel the urge to return to the easy path back to the shadow. But there is no worries, you are not alone. There are people with you along the path. Some may be behind you, besides you or ahead of you. You must learn to accept their help on your journey towards the light. Also learned to help the people around you as you can. If you see a person by you starting to head back to the shadow, you should try to help that person turn back around. It will be easy to let that person walk back or push them back to the shadow, and by doing so, you are also moving with that person back to the shadow. Remember, most of the time you won't realize that you are doing the pushing. The person being pushed will move faster back to the shadow, but the pusher will always slowly be moving behind them, making it hard to realize that both of you are heading back in the wrong direction.
All being said, don't be tempted to turn back to the shadow and denial. For example, saying, "....I meant this instead of that...." or if you believe that you should take a step forward with your left foot first, while the person next to you believes you should take a step with your right foot first. One must not deny that both of you are heading towards the light, the means of getting there is just different, but at the end,both of you are aiming for the same goal, reaching the light. At the end, it doesn't matter what belief system someone believes in. But for someone who believes and have reached a close understanding of God, knows that whether somebody is a Christian, Shaman, Jew, Muslim, or anything else, if they are heading towards the light then they are living God's will. And they should care enough for those who have lost their way from the light and help them by leading them back towards the light the way they believe in. EX: an atheist is living God's will by staying on the light path through his belief, science. Everyone lives with Godthrough their individual belief as long as there i. no denial in there inner self.
