The New Testament teaches that Christ was baptized to “fulfill all righteousness” (Matthew 3:14–15)--what does this mean? In Matthew 3:14-15 it says, 


  And Jesus answering said unto him, Suffer it to be so now: for thus it
  becometh us to fulfill all righteousness. Then he suffered him.


Can someone please expound what Christ was referring to when He said that He should be baptized to "fulfill all righteousness" (I am specifically looking for what it means to fulfill all righteousness)?
After thinking about this for some time, and pondering on people's answers/comments, I think the answer is more simple--in my opinion.

If Jesus Christ, being holy, has need of baptism, then we definitely need it.

He set the ultimate example, and if we are to follow Him we should also be baptized. Jesus Christ's example was one of never varying from the strait and narrow path--being obedient to His Father's commands in ALL things. Thus, He showed his humility and obedience to the Father by being baptized to "fulfil all righteousness"

In Matthew 4:19, it says,


  And he saith unto them, Follow me, and I will make you fishers of men.


The Apostle Peter taught that baptism was a commandment in Acts 2:28.


  Then Peter said unto them, Repent, and be baptized every one of you in
  the name of Jesus Christ for the remission of sins, and ye shall
  receive the gift of the Holy Ghost.


How can we follow the example of Jesus, save we are willing to keep the commandments of the Father?
