[REBLOGGED from Utah Lutheran by Rev. Bror Erickson]
Luke 11:29-32 (ESV)
When the crowds were increasing, he began to say, “This generation is an evil generation. It seeks for a sign, but no sign will be given to it except the sign of Jonah.  For as Jonah became a sign to the people of Nineveh, so will the Son of Man be to this generation.  The queen of the South will rise up at the judgment with the men of this generation and condemn them, for she came from the ends of the earth to hear the wisdom of Solomon, and behold, something greater than Solomon is here.  The men of Nineveh will rise up at the judgment with this generation and condemn it, for they repented at the preaching of Jonah, and behold, something greater than Jonah is here.
The evil generation seeks a sign. Every generation that seeks a sign is evil. It betrays our evilness that we seek signs. Naturally we should just trust God’s word. We should just believe it. It is God who speaks. But we want signs. How often do we want signs? Ask yourself how often you have asked God for a sign before you were willing to act according to his will. We have a natural distrust of God. We don’t trust him. Like Gideon we keep laying out a fleece, asking the ground to be wet and the fleece dry, the fleece wet and the ground dry. In fact, I have even heard pastors tell their members to do such nonsense. God was patient with Gideon, but Gideon proved himself faithless and evil.
