If we knew all these dates and what he did for a living and what he looked like christians like you would say. "see Jesus left us his legacy, we know all about him"who="Michael"]
If Jesus was such a great man wouldn't one believe that christians would know much about this man?
They know nothing.
1) When was he actually born? No one knows
2) What did he do to support himself? No one knows.
3) What did he look like? No one knows.
4) What was the date of the crucifixion and resurrection? No one knows that either.
5) Was he married? No one can verify if he was or not, though christians don't want him to have been married.
No one really knows anything about a man that christians claim to be the greatest man that ever lived.
NO MAN (THAT WAS EVER BORN ON EARTH)... HAS HAD MORE INFLUENCE UPON MAN KIND THAN JESUS CHRIST.
As for your questions about Him...
Even though man cannot point out the day of His Birth
Men that were fighting against each other have climbed out of their trenches and sang together...Wars have stopped (for a day) to celebrate the memorial day that has been chosen to Honor Him.
Strangers from the east brought gifts to Him at His birth and one of the gifts was Gold...
The Bible does not say just how much gold it was..
Also the entourage that traveled with Him evidently helped in providing His needs.
Is it not bad enough that men have taken a statue/image/icon ...of a corruptible man and attempted to imitate his personage...
What do you think it would be like if and the millions that would be made if any one actually kew what He looked like.
The purpose That Jesus came to earth...
(to sacrifice his Life for the sins of man )
edivently that which is greater importance.
In the Old and New Testament it is written ..
First by Isaiah.
Isa 61:1 The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound;
Isa 61:2 To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn;
Isa 61:3 To appoint unto them that mourn in Zion, to give unto them beauty for ashes, the oil of joy for mourning, the garment of praise for the spirit of heaviness; that they might be called trees of righteousness, the planting of the LORD, that he might be glorified.
THEN BY JESUS HIMSELF
Luk 4:16 And he came to Nazareth, where he had been brought up: and, as his custom was, he went into the synagogue on the sabbath day, and stood up for to read.
Luk 4:17 And there was delivered unto him the book of the prophet Esaias. And when he had opened the book, he found the place where it was written,
Luk 4:18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,
Luk 4:19 To preach the acceptable year of the Lord.
Luk 4:20 And he closed the book, and he gave it again to the minister, and sat down. And the eyes of all them that were in the synagogue were fastened on him.
Luk 4:21 And he began to say unto them, This day is this scripture fulfilled in your ears.
Luk_19:10 For the Son of man is come to seek and to save that which was lost.
IS OF THE GREATER IMPORTANCE ....THAN MOST OF YOUR QUESTIONS
The greatest man that ever lived and those saying that, haven't got a clue about this man in any personal way other than stories written by other men that can never be verified.
Its a belief, its not a fact.
