I’m surprised no one stated the obvious. You select the light, then shift-click an object or body part that you want the light to point at. Select Edit/Point At or cmd- m on a Mac (It’s probably ctrl-m on a PC). The light will automatically point at what you selected. If you move the object or light it won’t point at the same object. If you want it to track an object select the light, click the modifiers tab, then plus, select point at on the drop down menu. Select the object or body part in the drop down menu and the light will track the object when it moves. This works with spot all types of lights and objects too. You can get M4’s head to track another object for instance, great for animations. You can also use a target helper object to make things easier.
Sorry to differ, but for distant lights that would produce some very odd lighting shifts, especially if the light was close to the zero point during an animation.
It really needs to have a set direction unless you are going for some special effect such as a fast moving meteor, and even then a moving bulb may work better for that.
The key point about a distant light is that it has the same effect across the whole scene, barring shadows, and that you only ever need to consider it’s initial drection and then leave it.
