This article is substantially correct: the fear of God is the fear of Love.
Yet I think we must add a reminder to it.
This Love, just the same Love, because He’s immutable, did erase every living creature from the earth but those in the Ark with the Flood, shortening sharply at the same time our lifespan subsequentely.
This same Love makes the demons tremble! This same Love requires a perfect hatred of evil!
This reminder is necessary, otherwise many people could not understand what possibly they should fear of Love, substituting Him with their fantasies or lusts, where love is seen as tolerating everything and everybody, ever ready to make any compromise with evil.
This Love is the only source of everything and will not tolerate anybody not responding to His call in the Kingdom. Not one ounce of evil will be tolerated into the new heavens and the new earth. Human weaknesses, yes, but not evil, cheating, self-love and self-justification.
For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment; and did not spare the ancient world, but saved Noah, one of eight people, a preacher of righteousness, bringing in the flood on the world of the ungodly; and turning the cities of Sodom and Gomorrah into ashes, condemned them to destruction, making them an example to those who afterward would live ungodly; and delivered righteous Lot, who was oppressed by the filthy conduct of the wicked (for that righteous man, dwelling among them, tormented his righteous soul from day to day by seeing and hearing their lawless deeds)— then the Lord knows how to deliver the godly out of temptations and to reserve the unjust under punishment for the day of judgment
This Love is the divine Love, not the human love, ready to compromise to preserve his peace, which is not the Peace of the Lord. The Peace of the Lord to this world is a sword, a fire.
In short, human love will be deemed worthy to partecipate in the eternal bliss of divine Love only through repentance, which definitely means (also) respecting His Commandments.
For this is the love of God, that we keep His commandments. And His commandments are not burdensome.
In spirit and truth, not in the letter; that is, a violent, sincere and unceasing struggle of our damaged will to be His image and to grow into His likeness.
Our failures will be many, but asking for bread we’ll not receive stones!
