What kind of idiotic tripe are you spouting now??? Do you deny that it is FAITH in Jesus Christ that brings salvation? No, not everyone will be automatically saved because we must accept the gift of God which is eternal life in Jesus Christ. Jesus said to preach the gospel so that ALL may know of the grace of God that brings salvation to all those who BELIEVE.
Sadly, not everyone WILL believe and receive God's gift of grace. They will NOT be saved because they rejected the gift. Others will not be saved because they thought they had to pay for the gift by earning it, meriting it or deserving it - and we can't and don't. By grace are we saved through faith and that not of ourselves. It is the gift of God, not of works lest any should boast.
God sent His son to Earth to redeem mankind....the human race which He created.
Then He decided to add a ton of conditions.....you must know Christ and be aware of His purpose for being here....you must accept His word that He is Who He says He is....you must accept the conditions that He sets for salvation to apply to you....if you think that you should do good works to merit the gift, you don't get it....once you get salvation, you cannot lose it (OSAS)...if you live in a part of the world like China or the Americas or Siberia....salvation issn't for you as a human because you won't hear of Christ for a millenium or so.
For a God who is all forgiving and all merciful, He sure put a lot of conditions on His GIFT of salvation....Basically, for a thousand years or more, only a handful of people were saved....the rest?????...oh well, just their luck not to have been born in Jerusalem I guess...
