From Niel Short’s My journey to open theism:
So, no. I did not become an open theist by reading a book or a pamphlet. Actually, I got there by reading the Bible. I will explain what I mean. After all, there are also more people than you can shake a stick at who came to extremely divergent theologies by, as they say (and I question), reading the Bible.
The Bible demonstrates that prayer changes the future because prayer motivates God to act in ways that he otherwise would not act.
1 Then Jesus told them a parable about their need to pray always and not to lose heart. 2 He said, “In a certain city there was a judge who neither feared God nor had respect for people. 3 In that city there was a widow who kept coming to him and saying, “Grant me justice against my opponent.’ 4 For a while he refused; but later he said to himself, “Though I have no fear of God and no respect for anyone, 5 yet because this widow keeps bothering me, I will grant her justice, so that she may not wear me out by continually coming.’ ” 6 And the Lord said, “Listen to what the unjust judge says. 7 And will not God grant justice to his chosen ones who cry to him day and night? Will he delay long in helping them? 8 I tell you, he will quickly grant justice to them. And yet, when the Son of Man comes, will he find faith on earth?” (Luke 18:1-8)
Absolute divine foreknowledge also contradicts the biblical view that it is possible for people to lose their salvation (something Calvinists have noticed and therefore hold to the view that it is not possible to loose one’s salvation).
