maybe there'd be less suffering, but I don't know. Plenty of wretched Christians out there, sadly enough. Mean spirited people from all religions, too. I don't know what that's about, honestly.
Maybe if Christianity was more widely accepted, we could have stronger families, less social disintegration, etc., but...then again...before the Civil War, there were plenty of "Christians" using The Bible to support owning other human beings. Some people have used Scripture to justify the oppression of women.
So...I don't know.
Jesus never called us to change the world, not really. Light unto a dark and dying world, yes. Salt unto the earth, absolutely. The big "change" Christians make is -in- each of us, and its not even our own doing...its the gradual process of being conformed unto the image of Christ Jesus, so He can reach others thru us. "die to self daily," etc.
Interesting question. Oh, and...welcome to CFnet, btw.
