Christian, let God’s distinguishing love to you be a motive for you to fear Him greatly. He has put His fear in your heart, and may not have given that blessing to your neighbor, perhaps not to your husband, your wife, your child, or your parent.
Oh, what an obligation should this thought lay upon your heart to greatly fear the Lord! Remember also that the fear of the Lord is His treasure, a choice jewel, given only to favorites, and to those who are greatly beloved.
— John Bunyan (1628–1688)
where is this John Bunyan quote (fear of the Lord) to be found please?
Is it in his book by the same name/title?
I believe you will find it in A Treatise of the Fear of God. I would refer you to this link. https://www.blueletterbible.org/comm/bunyan_john/a-treatise-of-the-fear-of-god/11.cfm
Hope that helps.
