Israel was so unaware of the times and the intentions of Yahweh when Jesus was born that they didn’t know He had arrived until aliens from another nation came and told them. When He had matured and was about to begin His work in the nation of Israel, they again needed to be informed. This time, it was the last prophet that spoke to them in the line of “the prophets of Israel”: John, son of Zechariah.
When John the Baptist introduced Jesus, he said that He was the One Who would take away the people’s sin. When the magi introduced Him, it was as a King Who was worthy of worship.
Until we have received Him as both, we have not yet received Him for Who He is.
