Does God know the future?

God & the TrinityIn theological review

The short answer

Yes, God knows the future fully, not by prediction but because he declares the end from the beginning and his purpose stands. Scripture says he knows our words before we speak them and our days before they begin, and Peter says even the cross happened by God's deliberate plan and foreknowledge.

The fuller answer

Yes, God knows the future, completely and without learning it as it unfolds. He does not predict the future the way a clever observer predicts weather, by reading trends and hoping. Scripture presents him as the one who declares the end from the beginning, whose knowledge covers what has not yet happened because he stands over time itself as its Maker, and because his own purposes for the future are settled in his hands. This is not merely a puzzle for theologians, because a God surprised by events could neither promise the future nor be trusted with the parts of our lives still to come.

Remember what happened long ago, for I am God, and there is no other; I am God, and there is none like Me. I declare the end from the beginning, and from ancient times what is still to come. I say, ‘My purpose will stand, and all My good pleasure I will accomplish.’

Isaiah 46:9-10 (BSB)

Isaiah makes God's foreknowledge a test of true deity. The idols of Babylon cannot tell what is coming; God challenges them to try, and then states his own credential: he declares the end from the beginning, and ancient times from what is still to come, and his purpose will stand. In context this is not abstract philosophy. It is God naming, generations ahead, the rise of a foreign king who would send his exiled people home.

Even before a word is on my tongue, You know all about it, O LORD.

Psalm 139:4 (BSB)

David brings the same knowledge down to the scale of one life. Before a word is on his tongue, God knows it completely, and the days of his life were written in God's book before one of them came to be (Psalm 139:16). Jesus likewise set limits honestly: the day and hour of his return are set by the Father's own authority (Acts 1:7), which assumes the Father knows what the Son, in his earthly ministry, said was not given to men or angels to know.

Jesus replied, “It is not for you to know times or seasons that the Father has fixed by His own authority.

Acts 1:7 (BSB)

Peter's first sermon ties God's foreknowledge to the cross itself: Jesus was handed over by God's deliberate plan and foreknowledge (Acts 2:23), yet the men who crucified him acted freely and are held responsible in the same verse. Scripture holds those two together without embarrassment. God's knowledge of the future is therefore not cold surveillance. It is the knowledge of the author of the plan, who knows the end because the end is his, and who still calls real people to account within it. Prophecy in Scripture rests on exactly this foundation, and so does the ordinary Christian practice of entrusting unknown tomorrows to a God for whom they are not unknown.

No answer here is a dead end. Follow the question on, test it in practice, or work the method yourself on the Dig deeper page.

Does God exist?Yes. Christians do not believe in God as a guess to fill a gap. We believe because the world he made shows his power and nature, and because he has spoken, first through the prophets and then in his Son. The question is not really whether there is evidence, but whether we will treat the evidence as what it is.If God knows everything, do we really have free will?Yes, we really choose, and our choices really matter, even though God knows everything. Scripture commands people to choose life, holds them responsible for what they intend and do, and in the same breath says God works in his people and overrules evil intentions for good, holding both truths together.Does God change his mind?God does not change his mind in the human sense of learning, erring, or reversing his promises. Scripture says he does not lie or change his mind and that he does not change at all, while also showing his unchanging character responding with mercy when people repent and judgement when they harden, exactly as he always said he would.What is predestination?Predestination is the Bible's teaching that God, before time, chose and planned the salvation of his people in Christ. Christians agree God is sovereign and that salvation begins with his choice, not ours. They differ, sometimes sharply, over how that choice relates to human faith and freedom, and the main readings are set out fairly below.Bible Character: IsaiahThe prophet who saw the LORD high and lifted up in the temple, volunteered to be sent, and foretold the child to be born and the servant pierced for our transgressions.Bible Character: DavidThe shepherd of Bethlehem who killed Goliath, became Israel's king, received God's everlasting covenant, and wrote many of the Psalms.Bible Character: PeterThe Galilean fisherman who confessed Jesus as the Christ, denied him three times on the night he was betrayed, was restored by the risen Lord, and preached at Pentecost.
