"But we did not use this right . . . " (1 Corinthians 9:12).
Why shouldn't I? It's my right! This sentiment lies back of many a squabble between neighbors, many a road rage incident, many court cases. Just because I was first in line, does not mean that I must go first. Just because I paid tax does not mean I must get the government benefits that everyone else gets. Just because I worked hard for what I've got does not require me to keep it all for myself. Those who enter most fully into their 'rights' are those who don't have to use them.
