Healthy fear sir, think of it like a cocktail shake, The father is the rooster, that only not delivers a message of warning against denial, he also gives another a warning after the denial, which is cited toHow about faith is not sight/proof, therefore it must be opinion 2Cor. 5:7?
I don't know about you, but my father was very loving, so I had no problem believing that God was perfectly loving,
so I always believed in Him without fearing Him.
However, later in life I realized that those who reject the love of the Lord should fear experiencing a just hell,
so both love and fear should motivate an atheist to repent.
And in-between the hen or little cockerels have a healthy fear, and behold some know the living gift of the fear of the lord and don't deny him.
Whilst some deny his healthy loving fear that made them tremble.
This is also cited that the unsaved will work out there salvation in fear and trembling
