The world feeds us dirt, grass, rock, gravel. Mud. If you didn't know there was more to life than playing in a mud pit then you would probably never leave it. But once you realized there were wonderful delights in the world like cheeseburgers, French fries, ice cream, doughnuts and sweet tea- you should never want to go back to the mud pit. The Word of God is that delicious buffet of wonderful things to savor and enjoy that is much better for us than dirt. Who doesn't delight in eating a piece of cake or the lick of an ice cream cone on a hot day?
Not everything in the Word can be compared to desserts. No- we can't live off of sugary doughnuts for the rest of our lives (not for a lack of trying though).
Theres also a lot of veggies and protein that we need to be the bulk of our diet- the things we don't prefer to hear about like things we shouldn't do, things we should do but don't want to, and things we need to change about ourselves. These necessities cleanse us from the inside out making us whole and healthy to be able to carry out the design that God has for us. We also need a lot of protein- things we have to chew on, pray about, and work out in our lives. These aren't easy to swallow but they help our muscles the most to keep us from getting weak.
