The Bible says God’s ways are as far above our ways as the stars are above the earth.  So far, in fact, that it cannot be comprehended by the mind of man or woman.  Why would the answer to one prayer be yes and the answer to another be no?  Why would there be a flood, a drought, a tornado?  There is no understanding it.  But by faith, we can trust that He does know, does care for us, does listen to our prayers, and does hold us in His hand, turning everything to His purpose, which ultimately is that we become more and more like Jesus.
