In what sense was mankind created in the image of a triune essence?

God created mankind in His image. Gen 1 >26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. > >27 So God created man in His own image, in the image of God created he him; male and female created he them. In the first verse of this passage, we read one of very few instances where the 1 God uses a plural pronoun for Himself. Perhaps God is not alone or unique in this particular image He is about to also share with mankind. In the very next verse, we also read one of thousands of instances of God using singular pronouns as He continues to do so throughout the rest of scripture. Trinitarians very often use v26 as support for their concepts but in doing so, they indirectly overlook v27's singular pronouns. So it seems like a deeper inspection is necessary. Are we triune? Are we eternally begotten? Are we an indwelling spirit? Question ***In what sense is mankind made specifically in the image of a triune essence?*** --- *Triune is defined as being 3 persons sharing 1 nature/essence. Please explain how humans are a triune image. This question is not inquiring how mankind is made in the general image of God; but rather, is asking **specifically** about the image of the 1 Diety of 3 persons: the truine essence.*
