I would not argue with Christians that say that our approach to life should be a reasonable response to Scripture, not generally based on unreliable dreams or visions, but Mark 14:13-16 has always perplexed me. It seems more magical than reasonable. How Jesus knew what He knew doesn't really worry me so much as the kind of indirect, imprecise, superstitious-sounding directions that he handed down to these disciples and expected them to carry them out without any question. Of course, they knew Him. They could see Him. They didn't have to test the spirits constantly as we do. Still, it seems strange. Jesus knew so much, why not just tell the disciples the name or the address of the place they were looking for? Why was he so strangely obscure? And, how God does or does not choose to do things is really not for me to question except in that it makes me wonder what kind of directions I should be expecting from Him.
