One of the truly amazing words in the Greek NT is the verb gegraptai. It is perhaps the most powerful proof of the doctrine of the preservation of Scripture and causes our love for it to grow by leaps and bounds.
Scriptures for Study: Notice the fourth category of gegraptai in reference to the Lamb’s Book of Life (Rev. 13:8; cf. 17:8). While these obviously do not relate directly to Scripture, they do underscore the significance of the perfect tense.
