Ecclesiastes 3:9 What gain have the workers from their toil? 10 I have seen the business that God has given to everyone to be busy with. 11 He has made everything suitable for its time; moreover he has put a sense of past and future into their minds, yet they cannot find out what God has done from the beginning to the end.
700 years ago a many people lived in Arizona and New Mexico. These petroglyphs, pictures hammered into the dark coating on these rocks, and a few stone foundations are all that remain of these people. We can only guess why they disappeared. We can only guess the meaning of the frequent spirals. Did they function as a solar calendar, plotting the position of a first rays of the sun, allowing villages to know when they should plant seeds? Were they religious or cultural icons, letting visitors know who lived in a particular area, like tags spray painted by gangs on city walls?
700 years from now, what will remain of your work. What will future archeologists guess about the artifacts you leave behind? Were you merely keeping busy with the business of life? Or were you building faith so future generations will thrive when faced with future challenges.
