What did the water pots being filled to the brim at Cana indicate about the joy Jesus will bring to Israel?
The water pots being filled to the brim at Cana indicated that when Jesus brings joy to the nation of Israel, that joy will be full. The miracle signified an overflowing, complete joy for Israel, not partial or lacking. This sign showed that the joy He will bring to Israel will be full and complete, not partial.
Les explains that in John chapter 2, the first sign or miracle was when He turned the water into wine and filled the water pots to the brim. This was to indicate that when He brings joy to the nation of Israel, it's going to be full. The text says this beginning of signs did Jesus in Cana of Galilee, and manifested forth His glory, and His disciples believed in Him. So the fullness of the water pots points to the full, complete joy Jesus will bring to Israel.
