We can see that God created all things according to their proper purpose of use. For example, He gave only two legs to the birds while He gave fins to the fish instead of legs. Some species have outstanding sight, others have a very good smelling or hearing power according to their way of living. Human body contains many providences of God, too. In short, only two parts of the human face dont have the perspiration holes; the surroundings of the eyes and the lips. Man uses the muscles around the eyes and the lips the most. So if there were the perspiring holes on the two parts of the face, they would cause quite a big inconvenience. After all, only a little careful look into the providence of creation of all things will make even the unbelievers recognize the living God as the Creator and His power and divinity.(Romans 1:20)
