His word has been handed down to us through the generations, those we remember and those centuries away from us, and He will not let his work die out because people find faith difficult, or are too busy to open their eyes to Him, or too hard pressed to see Him standing beside them, or are silly, selfish and disobedient, as we all are, a good deal of the time. Sometimes the fire leaps up so that no one could miss it. It reminds us, too, that we, His human servants, the priests of old time, and you and I now, are given the task of making sure that it is kept burning. He commissions us as He did our forefathers. Such images abound in the Bible.
All life is sacramental.
Wherever we stand is holy. Wherever we are God is speaking to us, and challenging us. To Moses he gives a great task, which Moses tries to refuse, forgetting it was not his weakness but God's strength that mattered. To us he gives great tasks and small, simple ones, and commonly we refuse them all, yet he continues to call us and to speak to us in the quietness of our hearts. Through them He reminds us that He speaks to each of us individually, and this although we are not the first he has spoken to, and will not be the last, for discipleship has been going on for a long time and is not unique to us.
