Romans 4:17 -- ....."God who gives life to the dead and calls thos things which do not exist as though they did."
Sometimes we feel feel pain from sickness. How can we go around saying the Christ has redeemed us from this sickness? How can we say that by His stripes we are healed?
God's way is to call those things that are not as though they are. And because we are made in God's image, we can also call those things that are not as though they are!
When God wanted to make Abraham a father of many nations, what did He do?
He changed the way Abraham talked. At that time, Abraham did not even have a single child from his wife, Sarah, because she was barren. So how could he become a father of many nations?
God changed the way he talked, How? By changing his name from Abram to Abraham, which means "father of many nations." Every time he said his name he called forth what God saw him already blessed with.
When Jesus saw the man with a withered hand, He didn't say, "My goodness! It is so withered!" He said, "Stretch out your hand! (Matthew 12:13). He called forth what he wanted. He looked at the paralytic and said, "Rise, take up your bed and go home!" (Matthew 9:6). He didn't see it the way it was in the natural. He saw the way God meant it to be and He called it forth.
I change the way I talk -- I see the way God meant it to be, and start calling forth my miracle.
