"The first reference in the New Testament on this great theme, coming from His own lips, is very significant. "Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill" (Matthew 5:17). His total commitment to God's written Word was the first thing He came to confirm!
There are so many reasons He has given for His coming...
---For the Son of Man has come to seek and to save that which was lost (Luke 19:10).
---I have not come to call the righteous, but sinners, to repentance (Luke 5:32).
---For I have come down from heaven, not to do My own will, but the will of Him who sent Me (John 6:38).
The last time Christ gives a reason for His coming is also significant. It refers to His second coming!
---And behold, I am coming quickly, and My reward is with Me, to give to every one according to his work (Revelation 22:12)." ICR
