The Word provides a connection to the Lord because he is the Word; that is, he is the divine truth and the divine goodness within it. The literal meaning provides this connection because in this meaning the Word has its completeness, holiness, and power, as I have shown in the relevant passage above [Sections 214-224]. The connection to the Lord is not apparent to us; it exists in our love for the truth and our perception of it.
The Word’s literal meaning also provides association with angels in heaven because within the literal meaning there is a spiritual meaning and a heavenly meaning. The angels are in these higher meanings. Angels of the Lord’s spiritual kingdom are in the Word’s spiritual meaning, and angels of the Lord’s heavenly kingdom are in the Word’s heavenly meaning. These two meanings unfold out of the Word’s earthly meaning when the Word is read by people who regard it as holy. The unfolding is instantaneous and the association forms immediately.
