The term “way” is Biblical. It is used in enough contexts to have lots of overtones. But the primary meaning when I use it is way of life. It implies a journey, which means it’s not something you just flip a switch to get.
Jesus primary concept of a Christian is a follower or a disciple. For him I think it was your orientation, the direction you are headed.
Obviously following Jesus has some cognitive content. You have to know about Jesus to follow him, and he taught things about the way, and about his Father. But a lot of it is about how you live: what your priorities are, how you treat others, spiritual practices.
What if you don’t have all the content right? Non-Christian ways have varying degrees of overlap with Christian ones. I am not saying that everyone ends up in the same place. I very much fear that they do not. I think, rather, that in the end we will find that the ways take us to one of two possible destinations: God and destruction.
Knowing where you’re going has obvious advantages. But as I said in the previous posting, God in his grace can certainly arrange to find people who are lost. There are many people who it seems to me are on paths similar enough to mine that I think they’ll end up the same place.
One of the challenges for me as a Christian is that I think many non-Christian paths are actually closer to the way of Jesus than many Christian ones.
I believe this position is similar to the current Catholic one, by the way.
