Religious Determinism and Free Will

Few would dispute the view that the theology of the world’s three main monotheistic religions (also known as the Abrahamic religions) are deterministic, It cannot be otherwise. If you believe that God is omnipotent and omniscient (come to think of it omnipotence implies omniscient, you cannot be all powerful without possessing total knowledge), There nothing irrational about a deterministic worldview, it is shared by most scientists and supported by the theories of causality.
Determinism in the form of predestination is expressed a few times in the scriptures. An example of a ‘hard’ determinism is described in the book of Exodus: God hardens Pharaoh's heart to make him deny Moses’s demand of ‘let my people go’. This example (and there are several similar ones) shows the teleological view of the Bible.

So, whilst the deterministic worldview of the montheistic religions rules out Free Will, that view stands in sharp contrast to the everyday religious practices. Through preaching and rituals worshipers are led to believe that their adherence to the tenets of their religion and performing good deeds is somehow rewarded in this life or in the afterlife thus implying that there is such a thing as individual Free Will. That contradiction between religious worldview and a religious practice is baffling. I wonder how theologian bridge what to me looks like a glaring incoherence.
