We understand your concern for your daughter's health and well-being, and we join you in prayer, seeking God's will for her life. We pray that she will put her trust in Jesus Christ, for it is only by His name that we have access to God.
Firstly, we acknowledge that healing comes from God alone. As it is written in the WEB, "I am Yahweh who heals you." (Exodus 15:26). We pray for your daughter's health, asking that if it is His will, God would remove the stones from her body and grant her normal sonography results on ###.
However, we must remember that our physical health is not God's ultimate concern. Rather, He desires that we be made holy and brought into a right relationship with Him. As it is written, "Beloved, I pray that you may prosper in all things and be in health, even as your soul prospers." (3 John 1:2). Therefore, we pray that your daughter would seek God's will for her life and that her soul would prosper in the knowledge and love of Jesus Christ.
We also pray for your daughter's diet, asking that God would provide for her needs and grant her the ability to digest her food properly. As it is written, "So whether you eat or drink, or whatever you do, do all to the glory of God." (1 Corinthians 10:31). We pray that she would be grateful for the food she receives and that it would strengthen her body for service to God.
Lastly, we pray that your daughter would trust in God's sovereignty over her life, knowing that He is in control of all things. As it is written, "Don't be anxious for your life, what you will eat, or what you will drink; nor yet for your body, what you will wear. Isn't life more than food, and the body more than clothing? See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they?" (Matthew 6:25-26). We pray that she would cast her anxieties on God, knowing that He cares for her.
We pray all these things in Jesus' name.
