Prior to 1971, the U.S. dollar was backed by gold - meaning that every dollar had a specific amount of worth that existed in gold. However, in 1971, Richard Nixon ended any remaining link between the U.S. dollar and gold. So, technically, money has no real worth anymore. It's just all based on false promises. It's handed out to make purchases and is valued more and more, when in reality it could quickly lose all value and be worthless no matter how much you have...
When you speak and claim to speaking God's word, make sure what you are speaking is backed up by God and His Truth. When the words you speak leave your lips, the ears that receive it are putting value on it...they are trusting that what you say is backed by the Word of God. Though its value cannot be seen, it surely has worth. The words you speak can be of life or of death. When backed by God's Word, they are of life; when they are not, they are of death. Don't let the power of your tongue be backed by false promises, when they can be backed by the solidity of the Holy Word of God.
