From the fruit of his mouth a man's stomach is filled;

With the harvest from his lips he is satisfied.

The tongue has the power of life and death,

And those who love it will eat its fruit. (Prov 18:20-21)

The heavens and the earth were created as God “said.” This universe was formed by God’s word, and all things were made through “the Word,” and without it (him) nothing was made. As the word is confessed and spoken with your mouth, creation occurs in your life, giving you life, as the Bible says, “Man does not live on bread alone, but on every word that comes from the mouth of God.”

We, having been created as images of God, rule over the earth. And it is with our mouth that we rule. That is why God has given us languages together with the ability to speak them. And with our mouth, we not only rule, but also participate in God’s creation work as the above scripture in the book of Proverbs says.

We Christians believe in God and his only Son, who came to this world as Christ, died and rose from the dead. Through Christ, God delivered us from the dominion of darkness, and brought us into the dominion of the Son. We were all transferred from the world of destruction to that of creation. We as citizens of God’s kingdom of creation, we are all new creations. Death no longer reigns over us, and we reign instead over death and the world of destruction by doing the same work of creation that God does.

We Christians all know the importance of believing: we all believe that Jesus is the Son of God, and the Bible is God’s Word. But when it comes to the importance of confession, we do not know it enough. Because of our negative confessions—those of unbelief, worries and anxiety, we see the work of destruction happening everywhere in our lives. Jesus said:

I tell you the truth, if anyone says to this mountain, “Go, throw yourself into the sea,” and does not doubt in his heart but believes that what he says will happen, it will be done for him (Mark 11:23).

Pay attention to “what he says”—not “what he believes,” or even “what the Bible says.” It is “what he says” that happens. That means, first of all, that if you do not say, nothing happens. God’s word is active and powerful, and you believe in it all right, but unless you put it in your mouth and say it, you will have no result.

God’s word is not only something that you need to believe with your heart, but also something that you need to say with your mouth, and do with your body.

No, the word is very near you; it is in your mouth and in your heart so you may obey it. See, I set before you today life and prosperity, death and destruction (Deut 30:14-15).

We modern people are so used to abstract ideas and principles that we often do not care whether they materialize or not as reality. We listen to God’s word, and are merely satisfied with the fact that we listen. Then, we say, “Amen,” to show agreement with what we hear. But God’s word is deeper than the metal level of agreement. We need to believe it in our hearts, and confess it with our mouths.

Having been kicked out of the Garden of Eden, we lost the access to the tree of life. But God has restored this access for us.

She (wisdom) is a tree of life to those who embrace her;

Those who lay hold of her will be blessed (Prov 3:18).

Meditate upon this scripture. It will be no use if you only have it in your heart. You need to take its fruit, and eat it with your mouth. And it is with the fruit of your mouth that your stomach is filled, and there, is your tree of life.
