Recently, I believe GOD directed me to a special story in the old testament. It was the story of Ezekiel who was in the valley of the bones; and he told him to COMMAND (prophesy) the bones to rise up and put on sinew, flesh, and skin; and to live/breathe again ... do you know the story I am referring to? I will try to locate it for you ... it's in Ezekiel 37:1-10.
Anyhow, I had a scrape on my right leg that took 2 years to heal; and I asked GOD why wasn't it healing since I have faith and certainly as much as a mustard seed ... then, I was led to that story in my next bible reading ... just happened upon it ...
I immediately felt impressed that I should do the same, so I commanded the skin on my leg to heal (in Jesus' name, just for insurance) ... and yesterday morning, after 2 years, I awoke and the scab had fallen off my skin ulcer and was healed underneath like it should be.
I praise GOD for that and thank him very much becuz I was getting kinda scared about this becuz it wasn't healing right ... but PTL, HE showed me what to do. Now, why am I sharing this with you? Becuz I don't think we have to speak in tongues to pray over ourselves (although if you want to, you can -- to edify your own faith).
I believe that we can and should exercise our faith more -- we can speak the word over our bodies now; out loud; and in English; and we will see the Lord heal us ... this is something that I am going to do more often now!
