It’s so real that medical texts have a term for it: psychosomatic disease. The person feels every symptom, but there is no sign of infection. Call it mind tricks.
He believes it and has it, though no trace of logical cause can be found.
The patient first believes he is sick. It worsens when he begins to speak about it. Then he acts sick. The doctor gives him a placebo, a sugar pill, and tells him he’ll be well so that he can experience a reversal of symptoms through his belief.
What works to sicken, also works to make well: believe, speak, act. This is not hocus pocus. It is science. It is also Bible. Death and life are in the power of the tongue — Prov. 18:21 KJV. Apparently, it is such a powerful dynamic that it works without the intervention of God.
How much more so with God’s intervention! Believe in your heart for your answer. Speak it in prayer. Act on your faith. To me, it makes no sense that the same skeptics who snigger at the positive confession quantify and scientifically classify the negative confession. Or do we only affirm the bad? A Christian affirms the good.
Faith can heal you. Faith can bring needed finances. Faith can answer prayer. If they tongue has the power to make a person psychosomatically sick, then it also has the power to heal.
