That's my point exactly. And that was a good passage. People can be very moral, very good towards their fellow man, very righteous, and act in an otherwise gracious way towards their fellow man, without being part of an organized religion.
Being good or moral doesn't meet the requirement though. The following passage applies:
John 14:6 - Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
If you like to read C.S. Lewis' short book 'Mere Christianity'is worth reading and deals with reasons for belief vs. excuses for unbelief.
