I did not say that content births our spirit did I? Content is vital to understanding what GOD means in his word. It is vital to interpreting his word correctly.
No one you are engaging with disagrees with that. A bit of tilting at windmills. Nevertheless, it is the Bible that tells us who Jesus is, isn't it? And who Jesus is is what the Spirit testifies to our heart AND mind. So having the Spirit testify to our spirit without the Bible would be him testifying to nothing but 'you are a child of God'. In which case, one can just go on their merry way and never bother to pick up the Bible.
I know you do not believe that. What you say in addition to a dismissal of the Bible as not the first cause of our regeneration, shows you do not believe that it is unnecessary. And what I mean as the Bible not being the first cause---well no one you are engaging with is saying that it is a first cause of regeneration. So straw man. We are saying, the Bible is necessary along with regeneration.
