So...

Why doesn't God just come over the loud speakers at a football stadium and announce His omnipotence? Why doesn't He run ads during prime time to tell the world His salvific message? If He's so powerful and so good why doesn't He reach us the way we want to be reached? If He's so willing to be our savior, why doesn't He send out a universal text message? Why is God so seemingly silent? Why?

Benedict XVI has a response...

"You shall not put the Lord your God to the test." (Duet 6:16) This passage alludes to how Isreal almost perished of thirst in the desert. Isreal rebels agaist Moses, and in so doing rebels against God. God has to prove that He is God. The Bible describes this rebelion as follows, " They put the Lord to the proof, saying Is He among us or not?" (Ex 17:7) The issue then is one we have already encountered: God has to submit to experiment. He is "tested" just as products are tested. He must submit to the conditions that we say are necessary if we are to reach certainty...We are dealing here with the vast question of how we can and can not know God, how we are related to God and how we can lose Him. The arrogance that would make God an object and impose our laboratory conditions upon Him is incapable of finding Him. For it already implies that we deny God as God by placing ourselves above Him, by discarding the whole dimension of Love, of interior listening; by no longer acknowledging as real anything that we can't experimentally test and grasp. To think like that is to make oneself God. And to do that is not only to abase God, but the world and oneself, too.
