Gerunds, infinitives, nouns, verbs, (both transitive and intransitives) are all forms of speech I have been using as I continue to "Hark" during my Advent Quiet Times this year!
HARK!---normally an intransitive verb has become for me an exclamation in all CAPS---
an interjection for listen up and pay attention!
This Advent season I'm harking. (present participle of the verb hark) I'm paying attention to God's word and joyfully expectant of all He has for me.
BEHOLD---another interjection for this time of expectant waiting for a coming of the king.
No matter how Christian grammarians say it or what part of speech they use.....
.....to hark and behold Jesus is perfect for this Advent!
