The Question of Signs
A Sermon on John 2:18-22
So the Jews said to him, “What sign do you show us for doing these things?” Jesus answered them, “Destroy this temple, and in three days I will raise it up.” The Jews then said, “It has taken forty-six years to build this temple, and will you raise it up in three days?” But he was speaking about the temple of his body. When therefore he was raised from the dead, his disciples remembered that he had said this, and they believed the Scripture and the word that Jesus had spoken. (ESV)
The question of a wrong desire for 'signs'; a right and wrong desire for signs; a lack of spiritual understanding demonstrated; an adulterous spiritual nature revealed; testing for the false; practical guidance.
