If people only knew about the unlimited supply of Manna from heaven then the world would no longer hunger or thirst again!
However, churches would never tell you about the Manna available to us from God in heaven for then all churches would go bankrupt and pastors would no longer have the means to take an eight week sabbatical with his wife with the money collected from innocent souls (aka churchgoers). Meow
The bread that is spoken of by churches and leaders is the physical bread which our ancestors ate from and died! (see John 6vs58)
When we listen to the words God has written in our hearts we begin to be less concerned about feeding our stomachs (physical) and more concerned about feeding our souls (spiritual).
The day we access the eternal manna from heaven is the day when children will never go hungry again and the woman at the well will thirst no more.
"For the bread of God is He who comes down from heaven and gives life to the world.”
