What does it mean that God 'sits between the cherubim'?

The phrase 'sits between the cherubim' conveys God's divine presence and authority. The cherubim, as guardians of the way to the tree of life, demonstrate that access to God is through a singular path—Jesus Christ (John 14:6). This reflects how God communicates with His creation and fulfills His covenantal promises. Moreover, in the context of liturgy and worship, the mention of cherubim emphasizes the idea that God in His holiness is approachable through the blood of Christ, who is our way back to communion with Him. This assurance of access is vital for every believer, affirming that God's presence is intimately connected with His saving work.
