Why God Become A Man, Why Christmas

Hebrews 2:14-18 

¹⁴ Therefore, since the children share in flesh and blood, He Himself likewise also partook of the same, that through death He might render powerless him who had the power of death, that is, the devil, ¹⁵ and might free those who through fear of death were subject to slavery all their lives. ¹⁶ For assuredly He does not give help to angels, but He gives help to the descendant of Abraham. ¹⁷ Therefore, He had to be made like His brethren in all things, so that He might become a merciful and faithful high priest in things pertaining to God, to make propitiation for the sins of the people. ¹⁸ For since He Himself was tempted in that which He has suffered, He is able to come to the aid of those who are tempted.
