Old Testament God vs New Testament God
I am confused with regards to the extreme differences between God in the Old testament vs God in the New testament, why are they so different, although they are the same?
By different, it seems to me that God is much more gruesome and punishing in the Old testament, going as far as allowing the death of children and blasphemers. Then God in the New testament is very kind, humble, and all about mercy and forgiveness.
This is causing a conflict in my mind, because I cant seem to find an explanation as to why God had to be punishing then forgiving?
Id appreciate responses from everyone, God bless!
