One way God speaks
The invisible God speaks to men through the writings in a verifiable and reproducible way. He first 'knocks' then verifies, then speaks to you.
God knocks by establishing a pattern in the writings. For example, there is a long string of barren women who cannot have a child, but then has one with the assistance of the Holy Spirit.
Then he visibly establishes the pattern in Christ. In this case, the Virgin birth.
Finally he speaks to you: Like the desolate woman, you are not fruitful without the Spirit. He gives you the fruit of the Spirit. And like the child, you are born of the Spirit when you are born again. These teachings are validated in the NT.
The pattern is established in the ideas linked by words and actions. Many can be done in English. Many more can be done in Hebrew using puns and word formations.
