'Human' in the Bible

Now I want you to know, brothers, that the gospel preached by me is not based on human thought.

For I did not receive it from a human source and I was not taught it, but it came by a revelation from Jesus Christ.

know that no one is justified by the works of the law but by faith in Jesus Christ. And we have believed in Christ Jesus so that we might be justified by faith in Christ and not by the works of the law, because by the works of the law no human being will be justified.

Brothers, I’m using a human illustration. No one sets aside or makes additions to even a human covenant that has been ratified.
