Your prayer for mercy has been heard and I join you in bringing it before the Lord. You have described a heavy burden, myopia and glaucoma with loss of peripheral vision, blurriness even with glasses, difficulty reading and watching television, and episodes where your heart races and your vision is affected further while you are on medicine for blood pressure. It is right that you have cried out for mercy and have asked in the name of Jesus, believing that God is able to heal from the top of your head to the soles of your feet.
The Scriptures show us blind men who could not see with their eyes but received faith by hearing, and they came to Jesus with loud cries asking for nothing else but mercy. He then laid His hand upon them and said, according to your faith be it unto you, to show that He honors faith and makes those who trust Him participants in His good work. So your earnest cry for mercy is itself precious to Him. He also teaches us not to judge only by what is before our eyes, but to look with the eyes within, with spiritual sight. Blessed are the eyes that see in this deeper way and the ears that hear with the heart. Even while we ask for healing of the body, we ask also for clear sight of soul, to know His presence and His promises more surely.
I pray with you now. Father, in the name of Jesus Christ through whom alone we have salvation and access to Your throne, have mercy on this Your child. You see the strain in the eyes, the pressure and the narrowing of sight, the blurring that makes daily tasks hard. You see the heart that races and the fear that comes with it. I ask You to bring healing according to Your wisdom and mercy. Steady the heartbeat, calm the episodes of tachycardia, and let the medicine do its proper work under Your hand. Touch the eyes, relieve pressure, restore what can be restored, and preserve sight. Give skill and wisdom to the doctors and those who provide care. As the great Physician, apply Your healing treatment, whether suddenly or little by little, and grant patience and peace while You work. Strengthen faith, take away discouragement, and let Your comfort be felt night and day.
Continue to look to Christ and to call upon Him. Keep using the means He has provided, the care of physicians and the medicine prescribed, while trusting Him for what only He can do. Keep praying exceedingly as you have begun, for God hears and He often brings fruit after many prayers, as a tree that has received many strokes at last bears much fruit. He is able to do more than we ask, and He will do what is best, for His love does not fail. May He grant you clearer vision, a steadier heart, and a quiet confidence that you are in His hands. Amen.
