I hear your point, but I don't get the impression that you're hearing mine.
IMO Einstein limited *himself* based upon his own *assumptions* about God. He may have *assumed* that God exists but God doesn't "care" for humans. That *assumption* was incorrect however, according to the world recognized "experts" on the topic of God. While Einstein is a valid and recognized 'expert' on GR theory, he's not a recognized 'expert' on the topic of God or QM.
Between Islam and Christianity, over 50 percent of planet Earth considers Jesus to be a recognized "expert" on the topic of God. If I'm going to select an "expert" on the topic of God, it's not Einstein. Whereas he seemed to believe in an impersonal "God", it's clear that he never developed a *personal* relationship with the God that he believed in. It's a pity mind you, but it was a *choice* that Einstein made based upon his own preconceived prejudices. Did Einstein meditate and pray? I have no idea. All I know is that while he did believe in God, he did not have a "close" or personal relationship with God.
Again however, that's a *choice* that Einstein made for himself, and it's definite not *reality* for everyone. The world's leading and recognized "experts" on the topic of God all seem to *disagree* with Einstein on this point. I know for a fact that Jesus *did* meditate and pray to God, since these acts are described in synoptic gospels as well as John. Jesus found value in that activity even when the answer was 'no' (his personal crucifixion).
According to the 'expert' I put "faith" in, it is possible to have a personal relationship with God. It takes *effort* of course, effort Einstein may or may not have made. My *experiences* however are based upon *effort*, specifically an *effort* to get to know God, and to commune with God.
I have discovered that while God's love toward me is unchanging, often the answers to my prayers are "no". It's not that God doesn't want me to be happy however, it's just that he knows that sometimes my *desires* aren't always in my long range best interests.
I appreciate Einstein's position on a wide variety of topics. He wasn't however particularly faithful to his wife, and therefore I wouldn't select his beliefs/advice/actions on that topic as the 'be-all-end-all' in terms of judging the value of fidelity in marriage. He also rejected QM, and it's pretty darn clear now that his position was not correct on that topic either.
Both Einstein and Jesus believed in something they called "God". In terms of deciding whether or not it's possible that God "cares" for human, or interacts with humans, there is some debate/disagreement between them. I know what Jesus suggested in terms of meditation and prayer worked to help *me* establish a personal relationship with God during my lifetime. I therefore have very little "doubt" as the to the "expertize" of Jesus on that particular topic. I also happen to know that Jesus suggested that fidelity in marriage was a good thing, and I have followed that advice in my life and in my marriage. I can tell you from experience that such advice was good advice as well.
In terms of selecting an "expert" on the topic of whether or not it's possible to have a *personal* relationship with God, I have to go with the world's leading/recognized "expert" on that topic, and it it's not Einstein.
