Luke 24:44 Then He said to them, “These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” 45 And He opened their understanding, that they might comprehend the Scriptures.
It's not about people. In the afterlife or spiritual world, you are no longer a person, but a spirit and the Lord is God.
It certainly does not. It is saying "the Word" (which is Christ, John 1:14), was with God and was God, and that this was the case from the beginning. This same Word then created everything. It is not talking "all of scripture is about the Lord."
