The mystery of King David (2)

We've seen the prophetical King David is Christ in the bible.
Then, what are the signs and clue through which I can recognize Christ, our Savior who is the prophetical King David?
Let's take a look into the life of King David.

2 Sam 5:3-4 (When all the elders of Israel had come to King David at Hebron, the king made a compact with them at Hebron before the LORD, and they anointed David king over Israel. David was thirty years old when he became king, and he reigned forty years.)

This is an very important prophetical point because it illustrates the life of the prophetical King David. Let's see how Jesus Christ who is the prophetical King David fulfills this prophetical point.

Lu 3:21-23 (When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: "You are my Son, whom I love; with you I am well pleased." Now Jesus himself was about thirty years old when he began his ministry.)

Why was Jesus Christ baptized at the age of thirty? He'd been too busy? No way!!
He fulfilled the prophecy as the spiritual King David. He could've done earlier but He waited until the time of the prophecy. As King David was anointed as King at the age of thirty should Jesus Christ be baptized as Spiritual King. Some may question " Jesus did not reign for 40 year as did King David. He preached the Gospel for only three years??"
Yes. Jesus Christ preached for only three years and ascended to Heaven. Then, what about the remaining term 37 years? Since He did not preach for 40 years leaving the prophecy unfulfilled, He is not King David?
No!! the bible says he is King David?? hmmm... How should we understand this?
Next time let's see why Jesus Christ did so and how He prophesied in regard of the remaining term 37 years.
