What is it about the number 40? In mathematics it is an octagonal number; in science it is the atomic number of zirconium. 40 is the name of a song by the Dave Matthews Band; it is a milestone birthday. The Bible is full of instances where God made major changes and transformations after the period of 40; it represents a level of maturity, stability and a time to move forward while making plans to do even bigger and better things that will leave a positive impact on the future…after all, it has been said “Life begins at forty.”
