"You call Me Teacher and Lord; and you are right, for so I am.John 13:13(NASB)
Some of the claims that Christ made would have been downright arrogant if they had not been true, but every sign He performed was the direct fulfilment of an Old Testament prophecy that was the identifying signature of the Jewish Messiah. He proved over and again that He was Who He said He was; Son of God and Son of Man, God incarnate, the Messiah of Israel, and Saviour of the World.
He had just broken the bread and passed the cup saying, "This is My body and blood that is given for you," and He had just washed the feet of those He had trained for 3 long years, yet they did not understand. They called Him Master, Teacher, Rabbi, Lord, and it had even been revealed to Peter that He was the Christ; the Seed of the woman, the anointed of God, the Messiah of Israel, and Son of the living God, yet still they did not understand. And so Jesus set about explaining in detail Who He was and What He represented: "You call me 'Teacher' and 'Lord,' and rightly so, for that is what I am."
He was the Teacher of Israel about Whom Moses predicted. He was David's Lord Who was to be given the throne of glory. He was the One about Whom John the Baptist declared, "Behold the Lamb of God, Who takes away the sin of the world." He was the Christ, the Son of the Living God.
Jesus was both Son of Man and Son of God - fully human yet fully God, of one Being with the Father through Whom all things were made, Who for us men and our salvation came down from heaven to be our Teacher, our Lord, our Saviour, and our God. We have been brought into the family of God and intimately joined to Christ, as His Body and Bride, to be His eternal witness to His eternal goodness of His never-ending grace.
We have been called, chosen, justified, sanctified, and glorified as His witnesses so that in the coming ages He might show the incomparable riches of his grace expressed in his kindness to us in Christ Jesus - the One that we call Teacher and Lord, Saviour, and Friend.
Loving Father, sometimes I become so familiar with walking with You, day by day, that I forget the wonder of Who You truly are. Excite in me a wonderment of Who You truly are and the amazing grace that has been bestowed upon me. May I live a life to the praise and glory of your wonderful grace. In Jesus' name I pray, AMEN.
