Our reading
An editorial interpretation.
The speaker sets out a condition of mutual trust: their faith in another person depends on that person having faith in them. It reads as a boundary about self-respect, refusing to give confidence to anyone who withholds it, while presenting belief as something exchanged rather than freely handed out.
