You are the establishing witness for your life.  God’s promises, and the whole Bible, are based around this principle: “Out of the mouth of two or three witnesses let every word be established” (Deuteronomy 17:6; 19:15; Matthew 18:16; 2 Corinthians 13:1; 1 Timothy 5:19; Hebrew 10:28)
On one side of every issue of life facing you are the devil, evil spirits, sickness, disease, death and poverty. They are all part of the curse that’s in this earth (Genesis 3:17-19) coming against you to take over your thinking.  But on the other side of the those issues is Jesus, your Redeemer, and all His promises to you.  He ever lives to make intercession for you (Hebrews 7:25) and has sent His angels to minister for you and to assist you (Hebrews 1:14).  And then there’s the Body of Christ, your brothers and sisters in the LORD, who are praying for you.
So, on one side of the issue is the law of sin and death vying for your attention, and on the other, the law of the Spirit of Life in Christ Jesus. You stand in the middle. You are the establishing witness.  The devil says you can’t, you won’t, you’ll never. But God says all things are possible to him who believes (Mark 9:23). It will always go the way you say (Mark 11:23). Proverbs 18:21 says, “Death and life are in the power of the tongue, and those who love it will eat its fruit.”
When you declare, “I can’t,” you put yourself over on the side of the law of sin and death.  But when you stand your ground and say, “In Christ Jesus, all things are possible to me,” you are headed for victory.  Always choose life.  Jesus and all the forces of heaven are behind you, backing you up,. “Therefore, holy brothers, partakers in the heavenly calling, consider the Apostle and High Priest of our profession, Jesus Christ” (Hebrews 3:1). Jesus is the High Priest of your confession of faith, seeing to it that it comes to pass.  Psalm 103:20 says that the angels of God listen for the voice of His WORD and go to work to bring it to pass. So speak God’s WORD in faith, and give your angels something to work with.  
Believing you receive your answer affects three realms of your being: spirit, soul and body. You are a spirit, you have a soul, and you live in a body. Your spirit man believes The WORD and receives it. Faith comes out of your spirit, not your mind, through hearing the WORD of God (Romans 10:17). The WORD of God hidden in your heart forms a firm foundation against which the storms of life have no power (Matthew 7:24-27). In these verses, it wasn’t the storm that made the man strong. Jesus said, “Whoever hears these sayings of Mine and does them, I will liken him to a wise man who built his house on a rock” (verse 24).
Your mind is part of your soul. The soul is made up of the mind, will, and emotions. The mind is the battlefield where the devil “shows” you that it’s not going to work this time! He tells you “You’ll never make it.” “There’s no way out.” “You can’t do it.” “You’re took weak.” “They can do it because they’re stronger than you are.” “You don’t have the background they have.” “You’re the wrong color.” “You don’t have enough education.” “There’s something wrong with your brain.” “There’s something wrong with your back.” He tells the same lies to everyone.  If you receive his lies and meditate (or think) on them – which is called “worry” – eventually you will speak of things that are not as though they were. As you get into action and speak your “faith” in the negative, something happens in the spirit world. Worry acted on becomes doubt and unbelief.  Jesus said, “For by your words you will be justified, and by your words you will be condemned” (Matthew 12:37). This planet operates on a system of words God created it with words and has made you in His image with the ability to speak and create your world with words of faith.
You’re the deciding witness.  Second Corinthians 1:20 says, “For all the promises of God in Him are ‘Yes,’ and in Him ‘Amen’ to the glory of God through us.” 
Faith filled words dominate the laws of sin and death.  God’s WORD is always yes and amen. Choose and speak what God says.

Choose life!
