God is a sea of infinite substance.

The image of God as a “sea” evokes inexhaustible plenitude: an immeasurable depth and breadth of being that no creature can contain or traverse. Read in a Damascene key, it gestures toward classical Christian teaching on divine infinity and simplicity—God as the uncreated source of all that exists, beyond all finite categories, yet truly “substantial” (i.e., not a mere idea or metaphorical force). The metaphor also implies human epistemic humility: one may enter the sea (participate in God’s life by grace) without ever exhausting it. Its significance lies in combining apophatic reserve (God exceeds comprehension) with affirming language about God’s real, overflowing fullness.
