What is the strongest evidence for the existence of God?

The Bible never sets out a formal proof of God. It starts by assuming God exists (Genesis 1:1). It does point to several kinds of evidence: the created world (Romans 1:20; Psalm 19:1), God's acts in history and fulfilled prediction (Deuteronomy 4:32–35; Isaiah 41:21–23), conscience (Romans 2:15), and, above all in the New Testament, eyewitness testimony that Jesus rose from the dead (1 Corinthians 15:3–8, 14). Christians disagree about which of these carries the most weight and how much evidence alone can do.

What the text says

Where readers differ

The words it turns on

• נָבָל nabal (נָבָל)

  Someone morally senseless, who lives as if there were no God to answer to. It does not mean someone of low intelligence. It is also the name of the boorish Nabal in 1 Samuel 25.

  Drift: In Psalm 14:1, 'The fool says in his heart, There is no God,' English 'fool' suggests stupidity or a failed argument. The Hebrew points to practical, moral godlessness: a man who acts as though no one will hold him to account.

• τεκμήριον tekmērion (τεκμήριον)

  A decisive proof or sure sign. Greek writers on logic and rhetoric used it for evidence that settles a case. It appears in the New Testament only at Acts 1:3, for Jesus' appearances after the resurrection.

• ἔλεγχος, ἐλεγμός elenchos (ἔλεγχος)

  A proof, test or convincing demonstration; the act of establishing that something is true. Used in Hebrews 11:1, 'the conviction (proof) of things not seen.'

  Drift: Hebrews 11:1 is often quoted as if faith means believing without evidence. The word itself is a word for proof and being convinced.

• πίστις pistis (πίστις)

  Trust, confidence, faithfulness; reliance on someone judged trustworthy. It is often based on evidence or testimony.

  Drift: Modern English 'faith' often means belief held against or without evidence. The Greek is closer to well-founded trust.

• ἀπολογία apologia (ἀπολογία)

  A reasoned defence, as in a law court. 1 Peter 3:15 tells believers to be ready to give 'a defence' for their hope.

  Drift: English 'apology' now means saying sorry. 'Apologetics', the reasoned case for faith, keeps the original sense.

• μάρτυς martys (μάρτυς)

  A witness: someone who testifies to what they have seen, as in a court. It is central to Acts 1:8 and Acts 2:32.

  Drift: English 'martyr' has narrowed to someone killed for their beliefs. In the New Testament the word is first about giving eyewitness testimony.
