"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
My dear brother in Christ, a man's belly is not only filled in the natural; it is also filled spiritually. What is being discussed here is not the food part of your belly - the part you feed with natural bread - but the part you feed by the Word of God, your spirit-man..
The Bible tells us, "The spirit of man is the candle of the Lord, searching all the inward parts of the belly." Proverbs 20:27 . By "the spirit of man," God us referring to the hidden man of the heart.
What you say will either starve or feed your spirit man. Pray for discernment, brother, so that you will recognize what is good, coming from God, and what is evil, coming from Satan. Satan is the father of lies. So please, learn to guard your heart! Put a guard before your lips. Because the destructive things you run around saying; your spirit man will respond to, because you are feeding your spirit with the words that you say, or the thoughts that you adopt.
Please, find a good bible teaching fellowship of Christian believers who can help you to interpret the Word of God accurately - and increase your understanding of who it is that you belong to...the Lord your Redeemer, the Christ Jesus!
Pray that you learn to Distinguish Between:
The Voice of the One Who loves you, and Who ever lives to intercede for you, who is your Healer, your Deliverer, your Redeemer, your Helper, your Loving Lord and Savior, your Abba Father, your Merciful Father, your Compassionate Lord, your Encourager, the Lifter Of Your Head, your Health, your Miracles, your Giver of Life, your Blessings, your Life More Abundantly, your Friend, your Teacher, your Light and Truth, your Faithful One, your Trustworthy One, your Hope, your Devoted and True One, your Refuge, your Strength, your High Tower, your Protection from the evil one, your Beloved, your Bridegroom, your Husband, your Righteous One, your Peace, your Joy in the Holy Spirit, your Salvation, your Wonderful Counselor, your Comforter, your Peace, your Reconciliation, God's Living Sacrifice, the One who Sanctifies you, the Giver of every good and perfect gift, the Lamb of God, and your Good Shepherd; --
etc, etc, etc, etc, etc, etc, .................
FROM The Voice of the one who hates you, who lies to you, who deceives you, who betrays you, who stalks you, who wants you dead, who wants you miserable, who wants to inflict pain upon you, who brings devastation to your soul, who wants you hopeless, who wants you to despair, who wants you to be in anguish, who wants you in bondage to sin, who wants to you to be his prisoner, who wants you sick, who wants your body filled with disease, who lives to bring your life to ruins, who cheats you, who robs you, who leads you astray, who is faithless, who accuses you, who condemns you, who criticizes you, who offends you, you sells you into captivity, who tortures you, who causes insanity, who causes fear, the Destroyer, the Accuser of the brethren, the Evil One, the Devourer, who Hates you, who Attacks you, who Divides you from the flock, so to Conquer you and Control you, to make you his slave.....etc. etc. etc.
The words "With the increase of his lips shall he be filled" means this: For you to overflow with God's blessing to the point where you've got joy, strength, steadfastness, victory, stability - ability to overcome, having authority, and the devil fears Christ in you - you've got to fill not only your heart, but your mouth too! With the Word of God, with revelation knowledge of Who Christ Is In You, with What God's Word Says About You, What Your Covenant Relationship Means, with the Attributes of God, Etc.
For Then, as the Word overflows out of you, it will begin to affect your soul, your heart, your body, your life. God brings life into your heart; however that new life needs continual nurturing, and proper feeding to bear lasting good fruit - to transform your thoughts, your imaginations, your mind needs training to bring it unto the obedience of Christ, to Receive The Mind Of Christ - Strengthening your soul, healing your wounds, healing your body, and directing the course of your life properly, Bearing the Good Fruit of the Holy Spirit.
