I know a Christian man who celebrated with his parents their 50th wedding anniversary. Two days later the parents shot themselves in a murder suicide pact. Cancer drove the parents to the end of their rope. They saw no reason to tie a knot and hang on. They committed the ultimate act of letting go.
Some people make it, but others are too weary from the fight.
They eventually go numb hanging on and life passes them by. The fight makes them bitter causing their friends to shun them. Others make it but they carry permanent scars that disable them for life. Pastor Steve lived through seven long years of criticism in his church. It drove his wife to alcohol, drugs and adultery.
