Humility is all about being truthful and honest.
Do not think that if you surrender to God you will be loser. You will not lose anything except bondage, frustration and suffering. That is all you will lose.
The Ultimate expression of Humility comes when we control our senses.
Understand suffering is a part of my karma, otherwise you will spoil your future karma also.
A virtue which is divine is humility.
Substance of Bhakti is Surrender and Humility.
