"I believe tongues is the entrance into the spirit realm. Paul says that when he prays in other tongues he does not speak to men but speaks mysteries unto God. 1 Corinthians 14: 4: “He that prays in other tongues edifies or charges his spirit up.” You know how I feel after one hour of praying in tongues? I feel ready to take on the world. My Spirit can get so run down and do you know that if your Spirit is run down it will affect your soul and your body? Do you know that your immune system is affected by the vitality in your Spirit? The Book of James says that when your Spirit leaves your body, your body dies. As soon as your Spirit leaves your earth suit, your earth suit has no energy to keep it alive.
It is your Spirit that is the mysterious power that is keeping your body alive? If your Spirit runs down; its batteries get low, your energy levels within your Spirit become so depleted that it affects your immune system, your emotions, your soul, your intellect, and your perspective on life.
So, when you pray in unknown tongues, the Bible says you edify your Spirit. I know that most times when I get ‘flu it isn’t because I was out in the cold, it is because my Spirit’s energy is run down by giving out, giving out, giving out until I don’t have inner strength to help my body and my soul maintain life. That is often why sickness and disease comes on people. I believe that if our Spirit was full of the anointing every day and we prayed in tongues regularly, we would avoid most illness. Paul said, “I pray in tongues more than all of you” “I wish you would all pray in tongues” he said to the Corinthians.
There is no formula attached to this. Sometimes I pray two to three hours and nothing happens. Sometimes I have prayed for five minutes and everything has happened. So there is not formula to this but I as a regular lifestyle I think it is wise to pray regularly in tongues. Just build your Spirit up".
