Who is God?
God is the Creator who holds everyone and everything together. He is holy, unchanging, and without beginning or end.
“In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made.”
Every other question about God is downstream of this one. Before we ask what God wants, or how to reach him, we need some sense of who he actually is — because a vague or invented god can’t bear the weight of an actual life. Scripture doesn’t offer a definition so much as a description: God is the one through whom everything else exists, and who existed before any of it did.
“For I the LORD do not change; therefore you, O children of Jacob, are not consumed.”
That’s a striking claim: God’s unchanging character is the reason his people are still standing at all. If God’s patience, justice, or love shifted with circumstances the way ours does, no relationship with him could ever be trusted. His constancy isn’t a cold fact about theology — it’s the ground something else can be built on.
This is also why Christians have historically described God as self-existent — not made, not dependent, not explained by anything outside himself. Everything we know has a beginning and a cause. God doesn’t fit that pattern, and that’s exactly the point: he’s not one more thing inside the universe, he’s the reason there’s a universe to have things in at all.
Hard questions
How do we know that God is real?
Not by a single knockdown proof, but by a weight of evidence Scripture says is genuinely there for anyone willing to look. The sheer intricacy of the world — from the scale of the universe down to a single cell — points beyond itself to a maker. Paul goes further, arguing this evidence leaves no one with a real excuse: “his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made” (Romans 1:20, ESV). Add to that the near-universal human sense of right and wrong, something hard to explain if morality is just biology.
Why should we think this God is the only true God?
Because the God described in Scripture claims something no other account of God does: that he doesn’t change, doesn’t compete with rivals, and isn’t one option among many regional deities. Malachi 3:6 isn’t a modest claim — it’s the kind of thing only the actual, singular Creator could truthfully say. Every other religious system either describes many competing powers or a force without personality; the God of the Bible claims to be both singular and personal.
Who created God?
The question assumes God is a created thing like everything else we know — but that’s precisely what Scripture denies. Everything within creation had a beginning; God is outside that category entirely, without beginning or end. It’s genuinely hard to picture something with no starting point, because everything in our experience starts somewhere. But that difficulty is a limit of our imagination, not evidence against the claim — an eternal, uncaused Creator is exactly what it would take to explain why anything exists instead of nothing.
