Christ Jesus was born, walked, taught, and died, in the land that once belong to all Twelve of the Tribes of Jacob/Israel. It was fitting because during this time, the princes of the Gentiles occupied the land. Christ exposed the leaders of the world, for all to see; and so it is in 2013.
These worldly leaders constantly confronted Christ. They ask "By what authority[Matt.21:23,Mark11:28,Luke20:2]?" These worldly leaders were following the "Traditions of men", which is the doctrine of Satan, Kenites, and the uninformed.
Christ "taught as One having authority" and set the stage for the Gospel of the Kingdom of Heaven to be spread around the earth-after the death sentence was paid, the Gospel ran. Christ Jesus had authority because He was Immanuel, and on assignment. Much work had to be done between being baptized, and the Cross.
Not only was Christ authorized, but He gave His twelve disciple "power, and authority over all devils, and to cure diseases." The twelve were commissioned to go forward, and continue making disciples all over the earth. Christ Jesus taught as one having authority-because - He did. Why the confrontations, that eventually lead to murder? They needed Christ Jesus, to submit, to their authority!
