We were made in the image of God. He gave us authority to speak things into existence.
God spoke it, and it was so.
As believers, God has given you authority to speak it, and if you believe it, without doubting, it will be so.
Genesis 1:3 (KJV) – and God said, let there be light: and there was light.
Mark 11:23 (KJV) – for verily I say unto you. That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.
