The book of Proverbs delivers a practical meaning of the spiritual gift of the fear of God: "To fear the LORD is to hate evil; I hate pride and arrogance, evil behavior and perverse speech" Proverbs 8:13.
Is not precisely hate, because hate is a passion, the fear of God is the aversion to evil. An example of what is the aversion to evil, we see an example in the parable of the prodigal son (Luke 15:11-32), when the misguided son asks the father to advance his inheritance to waste it, the father tells his son: "son, I can not follow your path", aversion is rejection without passion. Aversion is then what makes forgiveness possible, whoever hates cannot forgive.
This is very important because the gift of fear of God is very close to the spiritual gift of Charity, and Charity is love without passion: "Love is patient, love is kind. It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs" 1 Corinthians 13:4-5.
The gift of fear of God can be described in many ways, but perhaps the most accurate would be to say that the fear of God is devotion, constancy, firmness, stability, and equanimity. In any case, this definition given by proverbs is very important to explain why the wise and the foolish, the good man and the bad man, generally cannot lead a common life or live together; the good and the bad mentality oppose each other like day and night. In their way of thinking, both the fool and the wise consider that they proceed logically, but just as the wise reject error, the fool rejects wisdom: The way of fools seems right to them, but the wise listen to advice. Proverbs 12:15.
In practical terms we can express this in another way, just as among the good everything tends upwards, because the upright seeks what is superior, that is, wisdom; perversion is like a well, because everything tends downwards, in other words, perversion, the deeper it is, the more it attracts the fool.
