The wound of an oyster — a grain of sand inside — is where a pearl comes from. A single grain of sand, unable to be washed out, is the cause of a pearl growing in order to protect the oyster. So it is with our life as well. The Christian will know be wronged and know injury. How are we to respond so that pearls growing in us?
God will not allow our lives to be injured beyond what He has ordained for us, nor can we be wronged past His using it for our benefit. The God of all the universe, who is just and righteous, will judge according to His unfathomable ways and care for those who are His own. So our duty is to bear wrongs when inflicted, and when faced with injustice to bathe lives around us with love. By doing this our soul becomes a pearl.
