My thoughts are a mess most of the time, like a liquid waiting to be poured into a mold. The mold is my words. We don’t really form our thoughts fully until we open our mouths to speak them, or write them. In fact, try to image everything that you would want say before you speak. You can’t do it, because thoughts only take shape as they are combined with words. It’s a mystical meeting designed by God.
Though God isn’t bound by our limitations in this respect, interestingly He chose to use words to complete His work. In Genesis, clearly God knew His own mind, but no action took place until he spoke. Then creature occurs. Jesus is the “Word of God” not only because He is the vehicle of communication, but because he is the embodiment of God’s most perfect action. He was in that sense “spoken” into human form and human history – “the Word became flesh and dwelt among us”. When Jesus speaks people are healed, the dead are raised and demons flee.
Likewise, we are condemned or acquitted by every careless word since each word is an action. From the overflow of the heart the mouth speaks and thus gives form to the formless thoughts inside us. We are saved when we believe in our hearts and confess with our mouths that Jesus is Lord, (Romans 10).
This works in our favor. In the praises of God spoken aloud there is power that does not exist when they are kept inside. Once they are spoken, they exist in the objective sense that they moved the air about us, entered our own ears and the ears of others, and rose to heaven as a testament. While we keep our thoughts inside, God still sees, but only he can discern their meanings. Once we speak, then we, and others, can too. It makes a difference when we speak our praises, and sing to one another in hymns, psalms and spiritual songs since the enemy, and the angels, can no more read our thoughts than men.
Words, spoken or written, give life to the raw materials of thought swirling about inside, bounced back and forth by feelings and circumstances; interrupted, forgotten, fleeting or profound.
