"For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counsellor, The mighty God, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even for ever. The zeal of the LORD of hosts will perform this.
(Isaiah 9:6, 7.)"
He's called by various names: Alpha and Omega, Good Shepherd, Son of Man, Lamb of God, Beloved Son, Prince of Peace, Light of the World, Messiah, Saviour, Emmanuel, Redeemer, Son of David, Almighty, Advocate, Bread of Life, Amen, and many more. This is because there's no single word that can qualify His entirety.
If there was just a single thing to talk about from the onset of creation till this very moment and the future to come, that would be about Christ. The Father (Jehovah) has given Him the power, the authority, over all principalities, powers, in heaven and beneath. So, we could say, "Christ before, Christ ever, Christ after, Christ to come, and Christ always." He is everything and anything to speak about. Only if you could understand the depth of what am talking about, you would get my point. We could keep speaking about Him from everlasting till eternity without getting bored or running out of words. Isn't that awesome?
