Tear people apart, so many wars have been started because of religion through out all of history. Yes it may create some nice people that do good deeds but the majority is bad.
The globe...we aren't there yet. As far as relationships and family, there is nothing more important than worshiping together. I am a Catholic married to a Muslim for 9 years....he is starting to see the light...our family will be forever be more stable, sacred, and pleasing to God.
It often tears even families themselves apart,which only proves what Jesus said as He told us this would be.He said"I came not to send peace,but division.There shall be five in one house, three against two and two against three....and a mans foes shall be they of His own household."Look at the division in Y/A over Religion.You have the believers and non believers,you have the believers debating over interpretation.There has always been trouble between people over Jesus.This will end when He returns and the whole world sees Him and realizes who He is.
