God is like a water bottle
Not only is it pure itself, but it purifies. Have you seen those "Liverite" commercials? It shows the animation of a liver wondering why the heart gets all the attention when it is the organ that cleans out the body's system of all that we put in it. Water does the same thing, it purifies and cleans out our systems. As the liver asks, "If that's not love, what is?"
So why do we always try to improve upon it? We add sugar, caffeine, coloring, chemicals, bubbly fizz, or fruit flavoring. The problem is that when water becomes too busy bringing those things into our bodies, how can it do the job of cleaning out our system?
God is like silence. Or at least He talks to us in it.
It is difficult to find a moment of silence in our busy world. The radio plays in our cars, when we go for a jog, while we work. Some people cannot even sleep unless they have the background noise of a TV. Most people cannot eat lunch alone, but need someone around to help fill the silence with conversation. It's possible to wake up in the morning and be so busy talking and listening to radio/television/other voices that we never have a moment of silence for God to speak. Even our prayer time often consists of us talking to Him.
And behold, the Lord passed by, and a great and strong wind tore into the mountains and broke the rocks in pieces before the Lord, but the Lord was not in the wind; and after the wind an earthquake, but the Lord was not in the earthquake; and after the earthquake a fire, but the Lord was not in the fire; and after the fire a still small voice. (1 Kings 19:11-12)
He wasn't in the radio, the TV, or the additives to our day, and if we don't sit still, we'll miss his voice.
Do we really need to rely on these machines and other people for our comfort? Do we need caffeine to give us strength? Are we putting our faith in things to give us what we need when they can never truly deliver what they offer and can only let us down? Do these things honestly satisfy, or do they leave us empty and run-down?
