All have sinned, including Gentiles. When Gentiles do the right thing, they are not sinning, but all of them have violated their own consciences and the law written on their hearts as well.

Therefore all are in need of salvation. Its just that the judgment on those who don't have the written law will not be as rigorous - yet it will still be for condemnation for the guilt incurred through sin.

There is only one adequate sacrifice for sin - Jesus Christ. All must hear of this. We cannot delay as others have done - we should have let the world know centuries ago. No one is good enough for God without Christ. Every person broke the law on their hearts. That is why we need to embrace our Saviour and then tell others about him.

Someone who is really searching for truth will find it. The fact is, of the unreached peoples, most are not searching for truth. They are living in the sins they know.
