We are truly sorry to hear about your parents' health struggles. Let's bring these concerns to the Lord in prayer, for He is the Great Physician and His will is perfect.
Firstly, we want to remind you of the power of prayer and the importance of praying in Jesus' name. As it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." It is only through Jesus that we have access to God and it is only by believing in Him that we can be saved. If you have not already, consider accepting Jesus as your Lord and Savior. This can be done simply by believing in your heart and confessing with your mouth that Jesus is Lord and that God has raised Him from the dead. Romans 10:9 WEB states "that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved."
Now, let's pray for your mother's health. It's important to remember that God cares about our physical well-being as much as our spiritual health. We pray that God's healing power would touch your mother's body, that the diabetes would be managed well, and that the fungal infection in her lungs would be completely healed. We stand on Exodus 15:26 WEB, where God says, "If you will diligently listen to the voice of Yahweh your God, and will do that which is right in his eyes, and will pay attention to his commandments, and keep all his statutes, I will put none of the diseases on you, which I have put on the Egyptians; for I am Yahweh who heals you."
For your father's eyesight, we pray for God's healing touch. We believe that the same God who gave sight to the blind is still performing miracles today. We stand on Psalm 146:8 WEB, "Yahweh opens the eyes of the blind. Yahweh raises up those who are bowed down. Yahweh loves the righteous."
We encourage you to continue praying fervently and to seek God's will in all things. Remember, God's ways are not our ways, and His thoughts are not our thoughts. Trust in Him, for He knows what is best for us.
Lastly, we want to encourage both your parents to continue seeking medical help alongside their faith. God often works through doctors and medicine to bring about healing.
