We eat the right kind of food in order to give strength to the body. Some people show a pure emotion of joy when it is time to eat.  They understand that the food will taste real good as it goes into their bellies and quench their hunger and release strength to their bodies. Now, shift with me to the meaning of this scripture found in Nehemiah .

Nehemiah 8:9-10 And Nehemiah, which is the Tirshatha, and Ezra the priest the scribe, and the Levites that taught the people, said unto all the people, This day is holy unto the Lord your God; mourn not, nor weep. For all the people wept, when they heard the words of the law. 10 Then he said unto them, Go your way, eat the fat, and drink the sweet, and send portions unto them for whom nothing is prepared: for this day is holy unto our Lord: neither be ye sorry; for the joy of the Lord is your strength. 

The Israelites had not heard the word for years because it was covered up while they were in exile.  But when the word was read and someone explained  the word it became substance that filled their empty hearts and released the fruit of Spirit called joy.  Joy is spiritual strength received when there is unveiling of the meaning of scripture.  Do not just read the word, ask the Holy Spirit to impart revelation and watch your strength increase by food called joy.
