via the Vatican:

The humble allow themselves to be challenged. They are open to what is new, since they feel secure in what has gone before them, firm in their roots and their sense of belonging. Their present is grounded in a past that opens them up to a hope-filled future. Unlike the proud, they know that their existence is not based on their merits or their “good habits”. As such, they are able to trust, unlike the proud.

All of us are called to humility, because all of us are called to remember and to give life. We are called to find a right relationship with our roots and our branches. Without those two things, we become sick, destined to disappear.

Jesus, who came into the world by the path of humility, has opened a way for us; he indicates a way and shows us a goal.

Dear brothers and sisters, without humility we cannot encounter God and experience salvation, yet it is equally true that without humility we cannot even encounter our neighbours, our brothers and sisters next door.
