Psalm 139:16 says all the psalmist's days 'were written in your book before one of them came to be,' cross-referenced with Qur'an Surah 53:32, implying exhaustive divine predetermination incompatible with free will.

This question is treated at length in this project's dedicated Free Will sheet; only the essential point is given here. Psalm 139 is worship poetry whose theme throughout is God's inescapable presence and intimate personal knowledge of the psalmist ('how precious are your thoughts to me, O God,' v. 17) — it is devotional celebration of being fully known and cared for, not a systematic philosophical treatise adjudicating the metaphysics of free will versus determinism. Classical Christian theology has developed multiple coherent frameworks holding together exhaustive divine foreknowledge with genuine creaturely freedom without collapsing into determinism: the Boethian/Thomistic view of God's eternal, timeless knowledge of the whole of history 'at once' (rather than an earlier temporal cause forcing a later effect), the Molinist account of divine middle knowledge, and various compatibilist accounts. None of these require reading Psalm 139:16 as a technical claim that God causally determines every choice; the verse is naturally read as affirming God's complete foreknowledge and providential care, which is a different claim from causal determinism.

Classical accounts of divine providence and creaturely freedom (Aquinas's doctrine of concurrence, ST I.83 and I.105.4-5) hold that God's causal action at the level of being itself does not compete with, but rather grounds, genuine secondary causation by free creatures — a both/and rather than either/or account.
