Your request has been heard and you are being lifted in prayer. Thank you for sharing so honestly that you are scared and do not understand what is happening with your body and your eyesight. It is right to bring that fear and uncertainty directly to the Lord and to ask others to pray with you.
The Bible shows that God cares about the healing of the body. The prophet Isaiah wrote that the coming Savior would bear our infirmities and carry our sicknesses, and Matthew, writing under the guidance of the Holy Spirit, points to Jesus healing all those who were brought to Him in the evening at Peter's house as the fulfillment of that promise. He broadens that prophecy to include physical healing, not only the forgiveness of sin. When Jesus broke the bread and said, this is my body which is broken for you, He was speaking of a suffering that covers the whole person. There is solid reason from Scripture to believe that physical healing is part of what Christ has provided, and it is right to sincerely ask Him for it.
At the same time Scripture keeps us from presuming that God wills immediate and complete healing in every case. Paul prayed three times for the Lord to remove what he called a thorn in the flesh, a messenger of Satan that buffeted him, and the Lord answered that His grace was sufficient. There is much about healing that we do not fully understand, why some are healed quickly and others are not, and why some healings are gradual. There is only one record of Jesus healing gradually, and that reminds us that God works in different ways. We believe strongly in healing, and we also recognize that any true healing process is from God, whether it comes in a moment or through the natural processes of recovery that God Himself established in the body. He heals physically, emotionally and spiritually, and even the ordinary workings of the body reflect His creative power.
The Lord also speaks directly to the fear you feel. Again and again when God drew near to His people, His first word was fear not. He said to Daniel when he was trembling, fear not, for from the first day you set your heart to understand and to humble yourself before God your words were heard. He said, fear not, for I am with you, be not dismayed for I am your God, I will help you, I will strengthen you, I will uphold you with my righteous right hand. Remembering that the Lord is present is the cure for fear. Fear and faith cannot rule the heart at the same time. When fear is allowed to take over, faith departs, but when we remember the Lord and trust His presence, fear loses its hold. Even when the future is unclear, you can know that He is with you in this valley.
There are two realities, the physical and the spiritual, and both are real. We naturally give great attention to the physical body, and that is good, but the inner person also needs to be fed. Prayer and time in the Word feed the spiritual life, and there is a close connection between the health of the soul and the health of the body. The Scriptures note that a joyful heart is like good medicine, and that the well being of the inner life affects the outer life. As you wait for answers about your health, continue to feed your soul with prayer, with Scripture, and with quiet trust in Christ.
We are praying for you now, that the Lord would touch your body and your eyesight according to His mercy and will, that He would give wisdom to any doctors who care for you, that He would grant you His peace that steadies the heart, and that whether His healing comes instantly, gradually, or through the means He has provided, you would experience His presence, His strength, and His comfort. The promise remains that the Sun of Righteousness rises with healing in His wings, and we ask the Lord to make His healing power and His nearness known to you in this time of need.
