On the expressway, you must be aware of the cars in front of you, behind you, and on both sides, or you may lose your life. Our success depends on our alertness. We must be sensitive to opportunities before they disappear. We should be alert to opportunities to witness for Christ, sensitive to speak to people who are spiritually open, looking for prospects for our Bible classes and church services. It is possible to cultivate alertness.
Most people make their living by enhancing a specialized alertness.
The auto mechanic is sensitive to the sounds of a motor. The teacher is alert to the classroom situation. The sportsman notices the movements and habits of wildlife. The doctor sees symptoms that others would not take into account. The lawyer is attentive to the mood of the jury.
