I Am That I Am
"I AM THAT I AM" (Hebrew: Ehyeh asher Ehyeh) is the divine name disclosed to Moses at the burning bush when he asked what he should tell Israel about who had sent him: "God said to Moses, 'I AM WHO I AM.' And he said, 'Say this to the people of Israel: I AM has sent me to you'" (Exodus 3:14). The phrase is linguistically related to the divine name YHWH (the Tetragrammaton, rendered LORD in English Bibles) and may be translated "I AM WHAT I AM," "I WILL BE WHAT I WILL BE," or "I AM THE ONE WHO IS" — all reflecting God's active, self-existent, and self-defining character as the one who is not derived from or dependent on anything outside himself.
The divine self-identification as pure being became foundational to theological reflection on God's aseity (self-existence) and immutability. The book of Revelation carries the same declaration into Greek eschatological language: "grace to you... from him who is and who was and who is to come" (Revelation 1:4), the divine name become an affirmation of eternal presence across all time. In the Gospel of John, Jesus' seven "I am" sayings and the climactic "Before Abraham was, I am" (John 8:58) — which provoked the crowd to take up stones for blasphemy — carry deliberate resonance with the burning bush disclosure, presenting Jesus as sharing the divine being expressed in the Tetragrammaton.
