thinkin about it, each line of "one man..." could be referrin to a different person, eg Christ, MLK, Gandhi, whatever.....
But with it refering to Christ here is my say:
"One man come in the name of love"
Jesus came to Earth with the message of love
"One man come and go"
Jesus came to Earth and left as well
"One man come, he to justify"
Well Jesus came to justify His Father's will and that of the scriptures.
"One man to overthrow"
Jesus had to overthrow Satan - take on the sins of the world and overcome them by getting crucified.
