Psalm 27:8 English Standard Version (ESV) You have said, “Seek my face.” My heart says to you, “Your face, Lord, do I seek.”
There will always be those who scoff at my testimony that God spoke to me. In the movie classic The Ten Commandments, Charlton Heston said that God spoke into his mind. This is perhaps the easier way to explain it to a secular audience. They could also think Moses insane, hearing voices being a neurotic condition.
Ephesians 3:16-17 English Standard Version
16 that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, 17 so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love,
This seat of choice is a residential place within us for the indwelling Christ. Vacant and unoccupied in the lost it is often described as a hole or emptiness in the heart. It is a longing for something intangible until it is filled by God. God speaks to us from there, not our minds.
This concept is unique to the New Testament as the Spirit was not given to man until after the resurrection of Christ. In the Old Testament all communication was external via angels or directly by God as in the case of Moses in the wilderness tabernacle.
The holy of holies within that tabernacle is a representative image of the heart of man.
The design and construction of the wilderness tabernacle is one similar to that of man.
Moses entered into the heart of the tabernacle to speak face to face with God.
Our hearts are where we can seek His face. Ref Psa 27:8
