“If one member suffers, all suffer together.”

The Bible has lots of commands and exhortations to believers. Obedience is automatic in the sense that it always follows from true faith. It is it not automatic in the sense that it just happens without any effort on our part.
And so it is here, when it comes to this principle of the whole body suffering when one part suffers. In one sense it is automatic because that is what it means to be a body. And yet we are also exhorted to weep with those who weep.
— Rev. Jerry Hamstra
