Some years after moving to the city, my cousin and I enrolled in swim classes at the Young Women's Christian Association. Where's the challenge of doing something so easy as swimming from one end of the pool to the other? I continue my classes, learning more and more each time I enter the water. The Apostle Paul told the members of an early Christian church: "May your whole spirit, soul and body be kept blameless at the coming of our Lord Jesus Christ" (1 Thess. 5:23).
