Anatomy

Try the following three movements:

1. Rotate your wrist in a 360 degree circle.
   2. Move your extended arm at the elbow straight up and down like a hinge on a door.
   3. Swing your arm in a circle at the shoulder.

Your arm is designed with three completely different types of joints to allow an amazing range of movement - from throwing a baseball to picking up a pebble and placing it overhead into a cup. Without all three of these very differently designed joints, this range of movements would be impossible.

Guess what engineers have discovered as they have worked to design robots used for everything from painting cars on an assembly line to the robotic arm on the space shuttle? They need to use exactly the same three types of joints! Every robotic arm has some combination of a rotational joint (similar to our wrist), a hinge joint (similar to our elbow) and a universal joint (similar to our shoulder). Yet, the manmade joints are crude, cumbersome, and wear out far quicker than those designed for our bodies. Isn’t it obvious the designer of our bodies was the greatest engineer of all?

Who hath believed our report? And to whom is the arm of the Lord revealed?

~ Isaiah 53:1
