Notice that Jesus Himself displays this change that should take place in our lives within - although He was without sin and entirely perfect, He still displays what our will should be as well:
Hebrews 5:7-8
Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;
Though he were a Son, yet learned he obedience by the things which he suffered;
A lot of times our obedience can come about because of the things that we have suffered have moved us to a change within that inspires a true faithfulness to a Great God. Suffering has a way of changing people - again, either for the better or the worse. There are those who have lost limbs that sit around asking why and are bitter against everyone. Then, there are those that have lost limbs that rather go on to bring about a positive message in the midst of their suffering. We all have a CHOICE in how we will allow things to change us.
Henry's Commentary
Here he has left us an example, that we should learn by all our afflictions a humble obedience to the will of God. We need affliction, to teach us submission.
Quotes
“When we are no longer able to change a situation, we are challenged to change ourselves.” - Viktor E. Frankl
“If there is no struggle, there is no progress. Those who profess to favor freedom, and yet depreciate agitation, are men who want crops without plowing up the ground. They want rain without thunder and lightning. They want the ocean without the awful roar of its many waters. This struggle may be a moral one; or it may be a physical one; or it may be both moral and physical; but it must be a struggle.” - Frederick Douglass
