Airports around the world have a strict screening process that all passengers and luggage must undergo before being allowed onboard, as part of the security system put in place to protect lives and prevent attacks. In the same manner, you must subject anything going into your heart to some tough screening, in order to prevent the wrong thoughts and information from taking root there.
God has given you the perfect tool with which to perform this screening—His Word. With the Word, you can filter out every false idea or thought that's against God's will. For example, if you get some information that's different from what God's Word says about you, don't dwell on it or allow it to process itself into your spirit. Reject it immediately and speak the Word. Say, “No, that's not for me! I function in the realm of super-abundance, because I'm a child of God and a joint-heir with Christ. Therefore, I can never be poor, sick, or confused.”
Use the Word of God as a filter to stop contrary information from getting into your heart. Reject thoughts of fear, sickness, lack, sorrow, corruption, and death that come from the world. Choose to embrace thoughts of success, victory, health, prosperity, happiness and fulfillment that come from God's Word.
Prayer
Dear Father, I thank you for your Word. I refuse to allow any thought that's inconsistent with your Word get into my heart. I fill my heart with the right information by meditating upon your Word always, in Jesus' Name. Amen.
