God will judge all people fairly based on the light and knowledge they had access to. Those who never heard the gospel will not be judged for rejecting Christ, but will be judged based on their own sin and failure to follow their conscience. All people are inherently sinful and fall short of God's standards, so without accepting Christ's sacrifice, all face ruin though not annihilation. God will judge both those with and without the written law based on their deeds.
