These two reasons cause you not to know if God exists or not? I could see if you left the church and either joined another denomination or just called yourself a Christian, but for acts of men to make you not sure if God exists, isn’t logical. Jesus Christ had to put up with invalid acts of pious men too and so did every believer you’ve read about in the Bible, and that didn’t make them doubt if God existed.
I am so thankful for people like you who are willing to tell me what I feel.
