The Bible teaches us that the power of life and death are in the tongue. The words we speak are power, they're creative, but they can also be death. Every time we open our mouths and speak, or even write, these words have an abundance of power that we cannot comprehend: they're often the driving force behind life itself.
We must guard and be careful of the words we speak to one another because they could be the words that that heal a heart, or drive someone over the edge. We have to guard what we say and how we say because we will be held accountable for every word we utter and, they way in which we uttered them.
Several years ago my dad preached a sermon in which he brought out an interesting point. Scientist discovered that our words are floating out in space. Radio transmissions of a speech Adolf Hitler made in 1939 were discovered using a special listening device, in space. This wouldn't have been so special, except that they were found thirty years after his death.
We must also consider that our actions, the words we say to people will affect them for the rest of their lives. When you tell someone that you love them, then you re-enforce those words with actions indicating your love, you had better be sure that those words are true. You can't tell someone one day that you love them, show that love with acts of affection and then the next day tell them that you were lonely and they just happened to be handy. To do this is like murder. You're killing their emotions, killing their heart and this could take them years to overcome.
Folks, the words we use, the acts we do must be based on truth. Our words and actions must be rooted and grounded in truth, in God's eternal love and must mean something. We have to be sure that we speak to people in love, that we act toward people in love and that we are mindful of the simple fact: every word we utter is a seed and every word we utter... one day we will stand before God to give account of. We'll also be required to account for the reaction those words had on people.
One last point, the Jewish sages believe that words are creative and every time we speak we're creating things. Don't forget, God created the heavens and the earth with His words. We're His children and the words we speak create just as His do. What we create, is just as important as what He created,
