God sends warnings to us to make us repent and go back to Him. Such alerts are warnings to us that a particular danger is coming, so as to wake up and go back to God. Such warnings could be a certain affliction, such as serious earthquakes that have shaken many countries and made people fear and consider them a sign of the beginning of the end that led to repentance.
God does not take sinners by surprise, His Majesty warns them. I like one of the monks' prayer saying: "Lord, do not take me out of the blue."
The divine warning may come before the fall, in order to make sure that those who repent are saved. God gave us this means so we can warn whomever we can from sinners. Unfortunately, some of those who bear the responsibility of warning people don't carry out their mission out of embarrassment, complement or compassion, so that their acquaintances or those they love are not annoyed.
Some warnings come in the form of incurable diseases such as AIDS, which is a warning for perverts, and many other diseases such as Virus C. Here the warning comes in the form of the death of one whom we love, so we can understand the lesson.
Devine warnings also come through certain events, such as the cholera epidemic of 1984, which left many victims in Egypt.
So, dear readers, if God sent you a warning, try to respond quickly and take advantage of it.
