There is a powerful principle in The Bible that we need to get a hold of. The principle of putting God's word in your mouth. From the beginning of time God breathed into man's nostrils the breath of life. Now, that breathe was not God blowing into man's nostrils. When he breathed into man's nostrils he spoke. Notice, Psalm 33:6 says, "By the word of Lord were the heavens made; and all the host of them by the breath of his mouth." So, the breath of God and the word of God are the same. And it was that breath that brought life into man's flesh. Man is the only creation of God that he spoke into. Because man is the only creation that can speak God's word. I don't think that is just a coincidence. He breathed his word into man because man is to breath his word out.
God originated the breathing process, breath goes in and breath goes out. I like that God calls his word breath because some people agree with putting the word in them, but they don't believe in the value of speaking it out. And when that word is taken in and spoken out it will bring life to your flesh and circumstances just as it did for Abraham and Sarah. Notice, in Romans 4:19 it says, "And being not weak in faith, he considered not his own body now dead, when he was about an hundred years old, neither yet the deadness of Sarah's womb." But, what did God do, he gave them something to speak that was in line with what he called for. They had to take that word in and release that word out. And that word brought life into their bodies. And God's word, the breath of life, can bring life to your body when you follow his instructions.
Notice Proverbs 4:20-23 says, "My son, attend to my words; incline thine ear unto my sayings. Let them not depart from thine eyes; keep them in the midst of thine heart. For they are life unto those that find them, and health to all their flesh. Keep thy heart with all diligence; for out of it are the isssues of life." When it says incline thine ear the idea is it is to come out of your mouth. They didn't have taperecorders and all the things we have now. It's an individual thing like in Deuteronomy 30:14, "But the word is very nigh unto thee, in thy mouth, and in thy heart, that thou mayest do it." Notice what God says his word is, life and health(medicine). And that word that is life and health is to be kept in your heart. Why, for out of it are the issues of life. Notice, you put the word in you for the word to come out of you. Jesus said it this way, "Out of the abundance of the heart the mouth speaketh." But, the thing I want you to notice is there is a result of you breathing that word. That word health is translated as medicine, remedy, and cure. Isn't that exactly what happened to Abraham and Sarah. They put that word in them and released it out of them and the result was the healing of their bodies(life came into their bodies). There's always suppose to be results of you breathing the breath of God. God told Joshua if he kept his word in his mouth then Joshua would make his way prosperous (Joshua 1:8). In Psalm 1:2,3 God says that he that meditates in his word day and night would be like a tree planted by the rivers of water, that bringeth forth his fruit in his season; his leaf shall not whither; and whatever he does will prosper. The word meditate in verse 2 means to speak, mutter, or utter. The breath of God was given to you to produce results.
