Some interesting answers to this question. One weakness of having a Holy Book is that we can only get out of it what we bring, so we each will have a tendency to tell others about God "Truths" that might actually be based on some idol or another. If God wills the salvation of all men, then he draws all to himself. Humans like to make country clubs, God does not seem to work that way. His love for the outcast, the sinner, would seem to suggest that we are all being drawn.
In the story of the Prodigal Son, if read, prayed over, can lead us all into some interesting thoughts on God and how he waits patiently for our return when we wander off. Also, at least for my part, it brings me to to the knowledge that I do not understand God's love or mercy, and for that I am glad.
Each human being is made in the image and likeness of God, that is why Jesus told us that how we treat others, especially enemies, is how in the end, we treat him. It is a hard road to travel, and for me, a slow journey in learning to see Christ, in others......be they believer, agnostic, or atheist. No limits on God's grace and love, at least from my experience. Well, by our freely chosen path, we can reject such an awsome, infinite, love.
Peace
