It came just now over the news that in spite of the threat of a tsunami people are still carrying on at the beach as if there was no warning issued.
It is the same when it comes to spiritual matters. Just now I am looking up the words “warn, warned, warning and warnings” in the concordance (Bible) and I find a lot of warnings in the BIBLE.
I remember what our teacher once said, when I was at elementary school (and that is long ago).
He said that those pupils who were already obedient, became even more obedient when exhorted and that those who were disobedient did not take much notice of warnings.
