Random thought

I am going to go out of the lines and be somewhat esoteric on this one. I think as we have moved further and further away from the time of Jesus, the further we have moved away from the true teachings and understanding of what he wanted us to learn and spread. Does it matter if some of the wisdom comes from the various Christian denominations, Gnostics, Islam, Hindu, Buddhism, or any other belief pattern, is not the main goal to become a better person and to find a form of salvation and to continue our journey?

I mean I know I have spent years trying to live a better life to do what is needed to find salvation and to move to the next step in the journey of the soul. I think we all are in our own way. That said is it not then on us to follow the teachings of accepting others and cast no stones if we are sinful? Then why do we spend so much time condemning others that follow a different path if their intent and their understanding go to the root foundation of the Christ's teaching? Just my opinion and thought.
