Breathing as Self-Evident Duty
The point: Direct people to understand that true love for brethren is most profoundly shown in secret intercessory prayer.
The duty to pray for one another is compared to the self-evident need to breathe to live, illustrating that some commands are so fundamental they don't need explicit articulation.
Number one, that the duty is so self-evident that it's difficult to find God commanding explicitly what is as self-evident as the need to breathe. If you want to live. I don't know a command in the Bible that says you ought to draw in your next breath if you expect to live. But because it isn't there, if you think because you can't get a text for it, you're at liberty to stop breathing, then go ahead and make your choice.
