Matthew 16:1-4 NIV
The Pharisees and Sadducees came to Jesus and tested him by asking him to show them a sign from heaven.  He replied, “When evening comes, you say, ‘It will be fair weather, for the sky is red,’  and in the morning, ‘Today it will be stormy, for the sky is red and overcast.’ You know how to interpret the appearance of the sky, but you cannot interpret the signs of the times.  A wicked and adulterous generation looks for a sign, but none will be given it except the sign of Jonah.” Jesus then left them and went away.
The Pharisees couldn’t see what was before their eyes – what greater sign could there be but God’s Son walking in their midst! Of course soon they would also witness the resurrection, how would they respond to that… Often I find myself asking God to show himself to me, before realising that he can be seen all around through the world he has made, through the family he has called us to be part of, and through scripture.
Father, thank you that you’re a god who doesn’t hide but has filled the world with signs pointing to him – give us the eyes to see.
