Determinism is true for the omniscient, omnipresent, omnipotent perspective. That perspective is not our perspective, and therefore for us, the illusion of free will exists whereas determinism is the absolute reality. It is important when discussing these things to keep in mind that there is multiple perspectives, none which look the same as another.

I liken this reality to a highly interactive movie. It seems very much like I live my life as I want to, making choices. But there is only one choice, the one we make. We could not ever have chosen differently (barring the existence of time travel) so choice is an illusion.

We are excempt from experiencing the deterministic perspective, but we can deduce its existence using logic and many have done so, therefore the existence of terms such as "divine plan", "fate", etc.

From the absolute perspective, we are all innocent. From ours, consequences of our actions have to exist. If there was to be a "Judgement Day", we would all have to be found not guilty.

Even the worst of us, merely playing a role in this divine comedy. Perhaps this understanding is at the heart of why Jesus asked us to forgive our "sinners" over and over again.
