Is there really such a thing as free will?
How can God give us free will if He is omnipresent and omniscient? Time is not a constraint for Him if He is, and was, and always will be. Since He knows everything, then He knows the decisions we will make and when we will make them.
For example, let's say someone prays for financial help on Monday morning. That afternoon, a check comes in the mail from an unknown source. That check had to be mailed before Monday morning in order to make it there that same day, so God had to move someone's heart before Monday to put that check in the mail. That would be before the recipient actually said the prayer. So God knew that the recipient would pray and make preparations before the prayer to get the check in the mail.
Let's say the recipient never prayed for help. Then God would know that person wasn't going to pray and may move the giver to give to someone else, if to anyone at all.
Since God is not constrained by our limits of time, then how can we really say we have free will?



perspectives
The apparent, illusory removal of free comes when perspectives are confused. Apparent paradoxes are possible when different frames of reference are confused. For example, an event takes place at 12:00:00 according to a high-velocity, relativistic traveler, while a stationary observer sees that same event happen at 12:00:01. Both are true. Which is observed depends upon the inertial frame of reference. Light is a wave. Light is a particle. Yep. Both are true, and it depends upon the kind of experiment performed. These things are not real paradoxes but merely appear to be so because incompatible perspectives or frames of reference are conflated. God can be omniscient and we can have free will. One is true from the Divine frame of reference while the other is true from a mortal's frame of reference. We certainly cannot occupy God's frame of reference, so there's no possible paradox from this direction. And while God was here in the person of Jesus, He was limited to our frame of reference (e.g.: Matthew 24:36; John 10:18; Philippians 2:6-7), thereby avoiding the paradox from that direction. By keeping the different frames of reference distinct, there is no need for omniscience to preclude free will.
