How do you maintain a connection to a Higher Power with so much suffering in the world?

If our higher power is a source of love, generosity, protection, and kindness, then why are innocent children being gunned down in schools, planes crashing in mid-air, and righteous people dying horrendous deaths from cancer? It doesn’t make sense. These individuals and their families are also praying for protection and safety, so why didn’t their higher power keep them safe? How can one maintain faith in a higher power’s power when such horrific events occur to innocent people?
