The Centurion recruited the Jewish elders to speak to Jesus on his behalf -- an interesting approach!. His understanding and faith seemed to clearly apprehend the authority of Jesus. This gentile had grasped what everyone else had missed -- Jesus had the right and authority to do whatever he pleased!
It looks like Jesus couldn't help but show compassion to this widow who had also lost her son when he stumbled upon a funeral procession. He had compassion and everyone, everywhere, heard of Him because of it. They drew conclusions about Him that came from the Bible.
I love the last line in Luke 7:35, "Wisdom is proven right by her children."
