Christ is the ultimate example of true humility.  He humbled himself to being willing to die a criminal's death on the cross to pay for my sin.
 
Philippians 2:3-11
Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. 4 Let each of you look out not only for his own interests, but also for the interests of others. 5 Let this mind be in you which was also in Christ Jesus, 6 who, being in the form of God, did not consider it robbery to be equal with God, 7 but made Himself of no reputation, taking the form of a bondservant, and coming in the likeness of men. 8 And being found in appearance as a man, He humbled Himself and became obedient to the point of death, even the death of the cross. 9 Therefore God also has highly exalted Him and given Him the name which is above every name, 10 that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth,11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
