(As it is written, I have made thee a father of many nations,) before him whom he believed, even God, who quickeneth the dead, and calleth those things which be not as though they were. - Romans 4:17
We have to be mindful of the words that come out of our mouths. God says that we have the power to speak those things into existence that are not as if they were! Want an increase in business, say it as if it's already happened! "I have more clients than I can handle." Looking for a new job, say it as if it's already happened! "I have a job that meets my every need." Want God to give you the desires of your heart, say it as if it's already happened! "God has given me everything I could ever want."
God used His words to shape this world into existence. If we're made in His image, why would it be any different?
We have power through our words and must speak God's truth even when we see (with our natural eyes) something different. It's imperative that you realize how you must trick yourself to get your mind (reality) to catch up with truth (God's reality).
The other day, I went to a friends house because she spent the night in the ER after having a migraine attack. She needed someone to come over and pick up her prescriptions to get them filled. When I walked into her house, almost immediately my head started hurting, I began seeing stars, all signs of a migraine coming on. Out of my mouth I said to myself, "Devil you are a liar. I do NOT have a migraine." Almost immediately the stars went away and the pain stopped. It was amazing. God reminded me that I can have anything I want -- anything that's entitled to me as a believer, if I simply speak it.
Be cognizant and aware of your words today, tomorrow, and forever. It is through your words that you shape the course of your life!
