I have been reading the book Quiet by Susan Cain… slowly but surely. I have read the part about introverts being slow to take risks and delaying gratification. When I read this, it made me feel that I was doing better than what I had anticipated (which I like finding out).
This idea makes me think of two things. The first the introverted nature of God. I would think of the multiple texts in the Bible that say God is longsuffering and abundant in mercy (lento para la ira y grande en misericordia in Spanish, which I like better) and see the principle of delayed gratification.
The second is the idea that INTJ trust works the same way. INTJs are slow to trust and delay the gratification of including someone inside their social circle until the other person has shown that they are worthy of my trust.
