While I don’t believe I comprehend this issue in its entirety and I am willing to be convinced otherwise, I currently believe that the trinitarian interpretation comports more with the Scriptures than the oneness interpretation. Here is why.
Therefore, getting this issue right is what I aim to do! That is, I want to study this issue into the ground. I want no questions unanswered, no issues swept under the rug, no items unstudied.

Why do you believe what you believe?" Jeff, in his typical quick and confident manner, replied: "The Word of the Living God!" Andy apparently wasn't adequately prepared to reply to this answer and responded with a weak, "Ok...". (It is even worse if you are watching the YouTube video because he follows up with a shoulder shrug and a smirk...)
...the question is: How did they know who Jesus was? A couple possibilities came to mind.
