God knows what we will choose but this foreknowledge is not what causes us to do anything. We cause our life to unfold as it does by virtue of our own decisions and actions.
“Every act ye meditate is as clear to Him as is that act when already accomplished. There is none other God besides Him. His is all creation and its empire. All stands revealed before Him; all is recorded in His holy and hidden Tablets.
This fore-knowledge of God, however, should not be regarded as having caused the actions of men, just as your own previous knowledge that a certain event is to occur, or your desire that it should happen, is not and can never be the reason for its occurrence.”
Gleanings From the Writings of Bahá’u’lláh, p. 150
That does not mean that
everything that happens to us is freely chosen. We do not choose our parents, where we were born, our heredity, and we do not choose accidents and injuries or diseases or our time of death. I think that some things happen because they were fated/predestined by God, but that does not mean that
everything that happens to us is predestined.
