If you examine these religions in their 'key teachings' they often say contradictory things. They cannot all be right!
If you throw away these 'key teachings' then you must believe that they all are wrong. If you throw away all the disagreeable parts, - there is no substance left.
Most religions put the emphasis on mankind working to seek Godís (or gods) approval.
Jesus Christ put the emphasis on a personal, loving God who has made a huge effort to reach out towards mankind. The Bible calls this grace - itís a 'free gift' from God for us. Jesus came to rescue us from the mess that we have made, because of our sins - the wrong things that we say, do and think.
Act 2:21 ďAnd it shall be that everyone who shall call upon the name of the Lord shall be saved."
