A popular bumper sticker says, "Don=t Get MadCGet Even.@ People demand what they perceive to be their rights, no matter how the demand harms others. Some go to court to squeeze every last cent out of those who hurt them. More and more violent crimes are committed each year. We need a strong dose of biblical truth to cure these attitudes. The biblical solution is gentleness.
The world might interpret gentleness or meekness as cowardice, timidity, or lack of strength. But the Bible describes it as not being vengeful, bitter, or unforgiving. It is a quiet, willing submission to God and others without the rebellious, vengeful self-assertion that characterizes human nature.
"The Greek word translated Agentleness@ was used to speak of a soothing medicine. It was used of a light, cool breeze and of a colt that had been broken and tamed, whose energy could be channeled for useful purposes. It also describes one who is tenderhearted, pleasant, and mild.
Gentleness is not wimpiness though. It is power under control. The circus lion has the same strength as a lion running free in Africa, but it has been tamed. All its energy is under the control of its master. In the same way, the lion residing in the gentle person no longer seeks its own prey or its own ends; it is submissive to its Master. That lion has not been destroyed, just tempered."
