The judgment is not a courtroom at the end of the world but the hour inside a person when awareness weighs itself and every part of the being is measured against the light. To fear and give glory is to hold the higher power in reverence and return the energy of attention to it rather than spending it downward.
Heaven, earth, sea, and the fountains of waters are the layers of the one person: the mind above, the body below, the deep of the unconscious, and the springs of feeling and vitality that feed both. All of these arise from the single source within, and the worship asked for is the whole being turning back toward that source. The reckoning happens now, inside, as a person aligns every level of the self to the light at its center.
Heaven: the higher mind and the realm of thought within a person
Earth: the physical body, the ground where consciousness takes form
Sea: the deep unconscious, the churning waters beneath waking awareness
Fountains of waters: the springs of feeling and vitality that feed body and mind alike
