Respectfully, I do not think you understand predestination at all, particularly in light of the fact you think it is indistinguishable from the atheist perspective.

As Dr Walter Martin used to note . . . there are not a lot of philosophical options.
If it walks like a duck, quacks, waddles, swims, flies, quacks, ruffles it's feathers, poops, bobs it's head, wiggles it's tail, . . . like a duck . . . it's probably not an elephand nor even a goose.
DETERMINISM = DETERMINISM. Wrapping it in white-washed robes of religiosity doesn't change the facts of it one bit.
Pretending things are so doesn't make them so.
Pretending things are Biblical doesn't make them so.
Pretending the Bible presents things in a one-sided 100% all determinism picture doesn't make it so. The Scriptures are clearly BOTH-AND. Evidently, God's REALITY that He's thrown us into is BOTH-AND. Pretending otherwise, doesn't make it so. Denying the mysteries involved doesn't make them go away.
You keep using this as proof of your position, but it's meaningless. God's predestining of all things is not in any way similar to the fowl of indiscriminate fate.
The difference, and this is critical, is between a determinism based on chance or whim or nameless fate or a false god like in Islam, and a determinism based on the concrete desire, design, decree and predestining will of the Trinitarian God of all creation as revealed to us in Scripture.
