Solid Source

In recent years, this expression, "according to sources," has become a means of announcing information that may not have been verified but, instead, is based hearsay and unsubstantiated claims.  So, when Paul announces that the news he is sharing with us is, as he puts it, “of first importance,” it’s not wrong to want assurance that what he’s telling us is based on fact.  After all, our eternal salvation depends on it.  And happily, that’s exactly what the apostle does.
