sounds like you are having migraine headaches...they cause the symptoms you are describing.
Someone whose conscience has been seared wouldn't worry or give a second thought to whether they had blasphemed the Holy Spirit.
In fact, they wouldn't give a second thought about God or seek Him out. Romans 12:1,2 says that we are to present our bodies a living sacrifice, and the next verse says to not be conformed to this world but be transformed by the renewing of our minds...we've been brought up since birth to think like the world, believe like the world and live like the world, and hence, the need to begin to renew the mind so that change can come into our lives, and we can know and do the will of God from the heart.
Father, I thank you for the wooing and drawing of the Holy Spirit in bebear's life, and I ask that you send forth your light and your truth into bebear's life. I thank you for the power and authority in the word of God to convert the soul of a person. I ask that you guide and direct bebear in the way they should go and that you would bring people of God who can minister truth and bring hope and wholeness through the power of the spoken word of God, through a believing heart. I thank you for the blood of Christ that purges bebear's conscience from dead works to serve the living God, and for the love of God poured out that was demonstrated and manifested when Jesus came to die in our place so that we can live life without fear of torment...1Jn 4:18 There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
In the name of Jesus, the word of God declares that for this purpose the Son of God was manifested that He might destroy the works of the devil, and so on the authority of that word, I call this work of the devil named migraines be destroyed. Pain, tingling, numbness, confusion, and distorted eyesight, get out! Be healed, body! in the name of Jesus. Thank you Jesus for taking and leading bebear into all truth. In Jesus' name I pray. Amen.
