You may say, If I say it when I don t feel it, then it is a lie . The Word is truth. Jesus said, Thy Word is truth. To agree with the Word of God is not telling a lie. To say with the Word of God that you are healed even though your body hurts is not a lie anymore than believing you are saved when you don t feel like it.
Light always overrides darkness.
The same thing is true for a lie and the truth. Truth will always change a lie, but a lie will never change the truth. Eventually, the symptoms go away. That should tell you something about the Word over your symptoms. Your symptoms are the lie and the Word is the truth .
