“A man’s belly shall be satisfied with the fruit of his mouth; and with the increase of his lips shall he be filled. Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.”
— Proverbs 18:20-21
Words are one of the most powerful tools we possess. With them, we have the capacity to build or destroy, to give life or to bring harm. The Bible makes it clear that “death and life are in the power of the tongue.”
Once a fascinating experiment was conducted where two plants were subjected to contrasting words. To one plant, life-giving and affirming words were spoken daily, while to the other, negative and harsh words were directed. Over time, the plant spoken to with words of life thrived, growing lush and healthy, while the one exposed to words of death began to wither and decay. This simple yet powerful demonstration shows how words can influence even the natural world around us, reinforcing the profound truth of Proverbs 18:21.
Let’s explore how words shape our lives and how we can use them to align with God’s purposes.
The Power to Shape Lives
Words shape lives—our own and those around us. Many of us carry the scars of hurtful words spoken to us, and most of us can admit to having hurt others with our own words. Words don’t just affect emotions; they have a profound impact on our physical and spiritual well-being.
Here are some examples of how words influence life:
- Negative Words and Sickness: Decades of negative speaking—words filled with fear, bitterness, or hate—can accumulate and manifest in physical illnesses or emotional burdens.
- Conflict and Destruction: Wars, divorces, and broken friendships often begin with careless or cruel words.
- Life and Peace: On the other hand, words of faith, blessing, and kindness create peace and build relationships. Those who speak life-giving words often experience lives free from unnecessary strife.
Our words carry the power to create or destroy. The question is: how will we use them?
Using Words to Bring Life
God has given us the ability to speak words that align with His will, creating life, healing, and destiny. Here are some ways Scripture teaches us to use our words to bring forth life:
1. Bring Forth Good Things:
“The good man brings good things out of the good stored up in him.”
(Matthew 12:35)
Speak positively about your future, allowing your words to shape a destiny filled with God’s promises. Only say what the Word of God says about you.
2. Command Obstacles to Move:
“Truly I tell you, if anyone says to this mountain, ‘Be lifted up and thrown into the sea,’ and does not doubt in their heart but believes, it will happen.” (Mark 11:23)
Faith speaks. and use your words to effect change.
3. Receive from God in Faith:
“Whatever you ask for in prayer, believe that you have received it, and it will be yours.” (Mark 11:24)
Use your words in prayer, expressing faith that God has answered it. Once you have prayed for something, align your conversation with what you have prayed.
4. Prophesy and Create Your Future:
“We have different gifts… if it is prophesying, then prophesy in accordance with your faith.” (Romans 12:6)
Speak words that align with God’s vision for your life, creating and making changes in your world.
A Declaration of Life
Here’s a powerful declaration to speak over your life. Let it shape your thoughts and actions as you align your words with God’s promises:
Life is in the power of my tongue, and I am satisfied with the fruit of my mouth. Out of the good treasure of my heart, I speak forth good things. God has put His words in my mouth—words of righteousness and blessing. My words are gracious and wise. I found His words, and they became the joy and rejoicing of my heart. He has filled my mouth with good things, renewing my youth like the eagle’s. I have the spirit of faith, and I believe; therefore, I speak.
