I remember the Sunday I did not cover my head to go to church, sometime last month. It is mandatory for workers in my church to do so but because it wasn’t really enforced in my previous parish, I took it lightly. Plus I actually didn’t really see any head gear to match what I was putting on. So, during the service i developed a heacache. If felt like someone was using a stick to knock my head and I immediately felt the Angels were at it. So I asked God to have mercy and promised I won’t ignore to wear my hat, beret, or scarf to church again. I told my family members of cause which was more like a funny joke but I knew to take it seriously and every time I go to church, I always remember. 

This, to some people, might be a very small issue. But whatever we face and whatever chastisement we go through should never be taken likely. 
The small headache i had, amongst other unfortunate events that I may have passed through is nothing compared to what our Lord Jesus faced and through these experiences the bible tells us he learned obedience. 
“Although He was a Son, He learned [active, special] obedience through what He suffered”

‭‭Hebrews‬ ‭5:8‬ ‭MSG 

The amplified version  says he learned trusting-obedience by what he suffered. Jesus had to face disgrace and a whole lot of fleshy denial and had to work against the impulses of the human will. He learned complete, total and trusting obedience and because of this we also have victory through Him.

We would have our own moments of training, humiliation, pains, denials, things that may be against our will but this is all part of a process to learn obedience and our perfection doesn’t come from the fact that we do not run into errors(cause we do), but our perfection is in Christ who also experienced everything we are experiencing and yet emerged faultless.

God always rejoices in the prosperity of his children. He does not want us to suffer. He may allow us go through our earthly tribulations so as to prepare us for the glorious prosperity of tomorrow.
