"Before. you were talking about serving God, which is very different."
Tell me pls, what is 'very different'?
Your talk of humanism is nothing but our cherished EGO, we hold so dear & guard it with our life which blocks our union with God.  Why bother with our human nature, i.e., our home made EGO that really don't exist except in our imagination when you can have God?
