One of the smallest muscle in our human body, the tongue does carry a lot of heavy responsibilities. Read here for a detailed explanation of the structure and functions of the tongue.
So I have been praying ceaselessly to God to remove this "mountain" (sores) and cast it into the sea - Mark 11.23. No matter how tiny our problem may seem to be, to the person suffering, it always seem to be the biggest. Sometimes, it is so big that he cannot deal with other things until this big problem is resolved or reduced to a smaller scale.
In the mighty name of Jesus, the King of all Kings, I command you the lowly canker sores to be removed from my tongue NOW!. Get out of my body, for mine has been cleansed by God, white as satin and sinless as ever. My God shall restore me in the original position that before this was and never shall you (canker sores) lay your feet on my body once more. You shall be buried deep into the sea and never to return to harm any human bodies!
God as stated in the scriptures, Jeremiah 1.9 - "Behold, I have put my words in your mouth". Your words are powerful and so it shall become mine as well. Therefore, I command you (canker sores) to leave my body immediately and return my speech and allow me to eat my food in peace and enjoyment like before!
Thank you Lord!
