Daniel 4:37 Now I, Nebuchadnezzar, praise and extol and honor the King of heaven, for all his works are truth and his ways are justice.

It was through Daniel, a Jewish captive, that the pagan king Nebuchadnezzar first came to hear about the one true God. The king came to understand his ways and his power, and came into relationship with the living God. Maybe that was the greatest legacy of the great prophet and visionary we remember as Daniel.
