Greetings! I will caution you to stick to the Bible. Do not "try atheism" as God views you dedicated.
"do not say before the angel it was a mistake" Ecclesiastes 5:6 Be careful for them who will
tell you that God is a trinity. Remember that not making an image of God is one of the ten commands.
I am reading Crisis of Conscience but I came to the conclusion on my own before reading it.
Somewhat boring, I suggest reading pages 168-169. In a nut shell; this is what was said of Russell;Pastor Russell
shall be a sign unto them shall tell them the truth about the Divine appointment of the trouble as
they consult his books ...his words shall be a sign of hope
I don't know what the organization is NOW, but back then, it was a cult.
For your son's sake imagine your new Christian freedom as more time to spend with him. Be happy! The Bible is a help. Keep it up!
Don't doubt God, He is for you. Preaching? I've been talking and talking, it is not on people's minds to know God. Do what you can
to be TRUE, especially to your son. Be helpful, cheerful when you can. I love you, sister!
