From an April 2002 general conference address.
Love One Another23966_000_003
In a general conference talk, President Monson told of a tree destroyed by a metal wedge that had become hidden inside it. He then explained how hidden wedges of anger or resentment can destroy our lives unless we learn to forgive.
I am acquainted with a family which came to America from Germany. The English language was difficult for them. They had but little by way of means, but each was blessed with the will to work and with a love of God.
Their third child was born, lived but two months, and then died. Father was a cabinetmaker and fashioned a beautiful casket for the body of his precious child. The day of the funeral was gloomy, thus reflecting the sadness they felt in their loss. As the family walked to the chapel, with Father carrying the tiny casket, a small number of friends had gathered. However, the chapel door was locked. The busy bishop had forgotten the funeral. Attempts to reach him were futile. Not knowing what to do, the father placed the casket under his arm and, with his family beside him, carried it home, walking in a drenching rain.
If the family were of a lesser character, they could have blamed the bishop and harbored ill feelings. When the bishop discovered the tragedy, he visited the family and apologized. With the hurt still evident in his expression, but with tears in his eyes, the father accepted the apology, and the two embraced in a spirit of understanding. No hidden wedge was left to cause further feelings of anger. Love and acceptance prevailed.
… In many families, there are hurt feelings and a reluctance to forgive. It doesn’t really matter what the issue was. It cannot and should not be left to injure. Blame keeps wounds open. Only forgiveness heals. George Herbert, an early 17th-century poet, wrote these lines: “He that cannot forgive others breaks the bridge over which he himself must pass if he would ever reach heaven, for everyone has need of forgiveness.” …
May we … harbor no hidden wedges but rather remember the Savior’s counsel: “By this shall all men know that ye are my disciples, if ye have love one to another.” 1
