The way in which the game was played was that a metal hoop was erected at a measured distance, and the children were given a bow, and ten arrows each. The objective was to shoot all ten of your arrows through the hoop. If anyone achieved that goal, and shot all ten arrows through, then that child was proclaimed a saint. However, if a child missed just one arrow, that child was named as a sinner. Of course, if a child missed with all ten arrows, (s)he was still designated a sinner! That child was no greater a 'sinner' than the one who missed with just one arrow! That was the rule of the game.
In just a couple of weeks, people all over the world will be celebrating the birth of a very special Baby in the Judaean town of Bethlehem. That baby grew to be the man, Christ Jesus. He never "missed the mark", but kept God's Law perfectly. He is the "... One Who in every respect has been tempted as we are, yet without sin." (Heb 4:15). All others have sinned, and 'come short'; so all of us need Him as our Saviour.
