📖 Biblical Definition
The Kalam Cosmological Argument argues: (1) whatever begins to exist has a cause; (2) the universe began to exist; (3) therefore the universe has a cause. The argument originated in medieval Islamic philosophy (al-Ghazali, 11th c.) and was revived for Christian apologetics by William Lane Craig (The Kalam Cosmological Argument, 1979). The Big Bang cosmology of modern physics provides scientific support for premise 2, making the argument especially strong in the late 20th and 21st centuries.
📜 Webster 1828 Definition
(Cosmological argument.) Whatever begins to exist has a cause; the universe began to exist; therefore the universe has a cause.

Medieval Islamic kalam tradition (al-Ghazali, al-Kindi); modern Christian revival by William Lane Craig. The argument's strength: it requires only that the universe began (a position increasingly supported by modern cosmology).
Once a cause is established, additional analysis identifies its features: timeless, spaceless, immaterial, immensely powerful, personal (since only personal agents can choose to bring temporal effects from a timeless state). The features cluster on God.
📖 Key Scripture
Genesis 1:1 — "In the beginning God created the heaven and the earth."
John 1:3 — "All things were made by him; and without him was not any thing made that was made."
Hebrews 11:3 — "Through faith we understand that the worlds were framed by the word of God."
Acts 17:24 — "God that made the world and all things therein."
⚠️ Modern Corruption
Modern atheism often appeals to multiverse or quantum-vacuum origins to escape the Kalam; both face their own causal questions and merely push the argument back a step.

The Kalam's simplicity is its strength. Two premises, both intuitive, both supportable by argument and evidence; conclusion follows by valid inference. The unbeliever must reject one premise: either things can begin without cause (philosophically problematic) or the universe didn't actually begin (cosmologically problematic).
Once a cause is established, the household's appreciation can build on the philosophical analysis: a timeless spaceless immaterial powerful personal first cause is what classical theology has always called God.
