What does the bread and length and depth and height represent in Ephesians?

In Ephesians 3:18, the dimensions of breadth, length, depth, and height illustrate the incomprehensible love of Christ and signify the expansive nature of the church, which encompasses all believers. This passage affirms that the church, as the new tabernacle of God, represents a spiritual dwelling of extraordinary dimensions where God's presence dwells. It stresses that this community transcends cultural and geographical boundaries, incorporating individuals from all nations, affirming God's desire for a diverse and unified body of believers rooted in His love. Hence, these dimensions speak to the surpassing greatness of God's grace and the intimate relationship believers have with Him.
