what is heavenly Christian food? is it the food we eat? well it depends on your faith if you think its wrong to eat....
Romans 14:20-23 (NIV)
20 Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a man to eat anything that causes someone else to stumble. 21 It is better not to eat meat or drink wine or to do anything else that will cause your brother to fall. 22 So whatever you believe about these things keep between yourself and God. Blessed is the man who does not condemn himself by what he approves. 23 But the man who has doubts is condemned if he eats, because his eating is not from faith; and everything that does not come from faith is sin.
