The heart communicates with the brain and the rest of the body in three ways that have been documented by scientific evidence: Neurologically (through transmissions of nerve impulses), biochemically (through hormones and neurotransmitters), and biophysically (through pressure waves). In addition, growing scientific evidence suggests that the heart may communicate with the brain and body through electromagnetic fields. Through these biological communication systems, the heart has a significant influence on the function of your brain and your bodily systems.
The heart and mind are intricately related, and that is why the Bible says what is in a man’s heart determines his actions and the words coming out of his mouth. If an individual’s heart is filled with negative thoughts--hatred, anger, jealousy, fear, worry, pride, bitterness, and strife--that is exactly what will come out of his mouth. If his mind and heart are continually filled with carnal thoughts and lusts of the flesh, it will be manifested in his speech.
On the other hand, if an individual’s heart and mind are filled with positive thoughts--thoughts of faith, love, joy, and peace--that is what will come out of his mouth. If his desires are centered on God and fulfilling His will, then he will speak forth faith-filled words. Even though a person claims to be a Christian and has an outward appearance of righteousness, if his heart and mind are not pure, his words will reflect this. Both blessing and cursing will come out of his mouth:
Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God. Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be. Doth a fountain send forth at the same place sweet water and bitter? Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh. (James 3:9-12)
A heart that is corrupted by greed, jealousy, anger, pride, bitterness, and unforgiveness cannot produce the fruit of good, wholesome words. The heart and mind must first be cleansed and renewed by the Holy Spirit. The good treasure stored in a believer’s heart and mind is the powerful living and written Word of God. Jesus said, “..the words that I speak unto you, they are spirit, and they are life” (John 6:63).
When your heart and mind are saturated with the Word of God, then you will speak pure, powerful, faith-filled words that are spirit and life to those who hear them. If the treasures in your heart are evil--filled with lust, carnal desires, greed, jealousy, anger, pride, bitterness and unforgiveness--then your mouth will spew forth evil things.
You are the one who determines what will come out of your mouth–whether it will be good or evil. Determine that today, only faith-filled words will come out of your mouth. Israel erred in their hearts, then they sinned with their mouths. God said: "Wherefore I was grieved with that generation, and said, They do alway err in their heart; and they have not known my ways" (Hebrews 3:10).
My FATHER, My God, this year let my life reflect the blessing of the Lord, I shall not be static, I decree PROGRESS, FAVOR, HONOR, AND INFLUENCE are my portion. My life is SALTED, My speech is SALTED, My Home and Business are SALTED in the name of Jesus.
