Gospel Lessons From Chocolate Milk, Part 2, Displacement

Recently I watched a Dave Ramsey video in which he drew an interesting analogy. I have been pondering about it for the last week or so. I've changed his analogy slightly, and have my own conclusions. Since I have another post about lessons I learn from chocolate milk, I'll call this part 2. 

Suppose you filled a glass with water and then poured a little bit of chocolate milk in it. The entire glass would become cloudy. If you continued to pour in chocolate milk, eventually all the water would spill out over the top and there wouldn't be any water left, just milk. 

Then suppose you took the same glass, which now contains chocolate milk, and started to pour water into it. At first there would appear to be little change. Over time, however, the glass would start to clear until all of the chocolate milk were displaced. 

We did this experiment recently for a family home evening. One of my kids noted that the water became cloudy much quicker than it became clear again. 

Now consider glass as our soul. The water represents things of the spirit, and the chocolate milk (for this example only) represents things that offend the spirit. 

23 And that which doth not edify is not of God, and is darkness.
24 That which is of God is light; and he that receiveth light, and continueth in God, receiveth more light; and that light groweth brighter and brighter until the perfect day.
(Doctrine and Covenants 50:23-24)

We can choose to fill our souls with light or darkness. 

 22 The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.
 23 But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness! (Matthew 6:22-23)

If we stop pouring milk into the class, it doesn't make the glass clean again. Water has to displace the milk--the milk has to be pushed out. 

Refining fire, go through my heart,
   Illuminate my soul;
Scatter thy life through every part,
   And sanctify the whole.
(Charles Wesley)

I've enjoyed pondering this analogy. I'd be interested to know what other lessons you can draw from the analogy.
