Do you not believe that some are especially elected before the foundation of the world?
And, do you not believe that Jesus is the only way to the Father and heaven?
No and yes...but not in the way you're accustomed to.
There is no predestination, only foreknowledge. God knows the end from the beginning, but he does not force anyone to do anything. He just accommodates for what he knows is coming. The elect are not "decided" from the foundation of the world. They are known from the foundation of the world though. Everyone has the possibility of being saved. Everyone.
I have a few questions for you. Is God just God of the Christian, and is the only way to God the way that we know? If God is the author of the universe, God of everything and everybody, then how can anyone say that some people are outside of God’s providence? Just because you and I cannot account for the religions of other people does not mean that the God whom we worship cannot.
I'd like to direct you back to the parable of the workers in the vineyard:
"Am I not allowed to do what I choose with what belongs to me? Or do you begrudge my generosity?’16 So the last will be first, and the first last." -Matthew 20:15+16
What will happen in the order of things if people either don’t get what they deserve, or, in this case, get more than they deserve? The moment we assume that God's grace is too little for people, we are putting ourselves in the place of God...which is precisely what sin is! Karl Barth, a famous German theologian reminds us of not only the greatness of God but also the “otherness” of God, which means that when we presume to speak about God at all we should do so at a distance and with the realization that we cannot speak of God as simply an immense version of ourselves. When we speak of God we do not speak boastfully or competitively, or in the sense that we know all we need to know, but we can speak hopefully and in faith that the amplitude of God is greater than our capacity to imagine or experience.
"For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. 15 They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them 16 on that day when, according to my gospel, God judges the secrets of men by Christ Jesus." -Romans 2:14-16
My beliefs are heavily influenced by Augustine. The real battle is in the heart, and God is the ultimate judge. I leave it to him to decide those who are saved and those who aren't, but I will not exclude anyone from salvation by their beliefs.
