Q. The lighthouse challenge ?
Yahshua said to let our light shine before men that people can glorify Yahweh. The Biblical Law is the only way in which we can glorify Yahweh. Without the Biblical Law, no-one in this world would know what to do. As a result, this challenge focuses on that. Someone is going to need help and only by giving them the correct Law will they be able to be helped. If you get the answer correct, the whole picture will be illuminated. If not, the picture descends in to darkness. The idea: If you're ever stuck, look to the Biblical Law.
