Augustine of Hippo

So this faith is also a rule for salvation, to "believe in God the Father almighty," creator of all things, "king of the ages, immortal and invisible." He is indeed the almighty God who at the origin of the world made all things out of nothing. He is before the ages and made and governs the ages. He doesn't, after all, grow with time, or stretch out in space, nor is he shut in or bounded by any material. He abides with and in himself as full and perfect eternity, which neither human thought can comprehend nor tongue describe.
