Imagine coming into an empty room after a long day of very hard work. Your exhausted, your feet and back ache, and your legs are weary. You are eager to sit down and rest. In the room, you see a chair. You approach it, look around it, and study its structure and features. Someone comes into the room and tells you that it is very sturdy—one of the best, made by a top manufacturer. As you look at it closely, you can see that it is well built. You now have a knowledge that the chair can hold your weight, in fact, you affirm the testimonies about its qualities, and you’re led to be fully convinced that the chair can provide a safe and comfortable place to sit and rest your body. Finally, you plop down and nestle into the chair.
