For with thee is the fountain of life. The ultimate source of all life is God. Israel had been taught by Moses (Deuteronomy 30:20) that God was their Life; but this was not all; he is equally the Origin of life to everything that lives—to angels, men, beasts, birds, fishes, zoophytes, plants (see Genesis 1:11, Genesis 1:20, Genesis 1:24, Genesis 1:27, etc.
). And, as he is the sole Source of natural life, so is he also the one and only Origin of spiritual vitality (Psalms 30:5; Psalms 66:9; John 1:4; John 6:57; John 7:37-39, etc.). And in thy light shall we see light (comp.
John 1:4, John 1:5, John 1:9; 1 John 1:5-7). God is essentially Life and Light. He "has life in himself" (John 5:26). He "is Light, and in him is no darkness at all" (1 John 1:5). The Son, who is "the Light of the world" (John 8:12), is hut "the Effulgence of his Father's glory" (Hebrews 1:3, Revised Version), "Light of light," the ray which streams from the Sun of the universe.
Yet from him comes the light which enlighteneth all creatures (John 1:9). "In his light we see light."
