Jesus Christ has accomplished great things! But how you say, did He do all that He did? Jesus Christ was sucessful because He became obedient to His Father's will; even unto death.

Philippians 2:6-10 King James Version (KJV)

6 Who, being in the form of God, thought it not robbery to be equal with God:

7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:

8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.

9 Wherefore God also hath highly exalted him, and given him a name which is above every name:

10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth
