Is God still big enough to save the world?

For a long time, I thought that the apostles had it easier than we do. They could preach and teach in their world, because the world was smaller, there were fewer distractions, and because most people already believed in something(s) supernatural. Today, we have to deal with atheists, agnostics, cell phones, round-the-clock news, genocide, and so many other things that make people doubt that anything exists beyond the life they're living now. My question is, has the God who made the world changed such that he can't save that same world today?
