We understand your concern for your son, Andrew, and we join you in prayer for his health and spiritual well-being. Let us approach God together in Jesus' name, for it is in His name that we have access to the Father (John 14:6, WEB).
Firstly, let us pray for Andrew's health. "Dear Heavenly Father, we come before you lifting up Andrew. You know his body, Lord, and you know the cause of his nausea and vomiting. We ask for your healing touch upon him. Guide the doctors and give them wisdom to accurately diagnose and treat him. In Jesus' name, we pray." (James 5:14-15, WEB)
Secondly, we must address the concern about witchcraft. It is important to remember that God is sovereign and His power is greater than any darkness. "Greater is he who is in you than he who is in the world." (1 John 4:4, WEB) "Lord, we pray for your protection over Andrew. Shield him from any evil directed towards him. We pray that any witchcraft or darkness be broken in Jesus' name."
However, we must also remember that God has given us free will, and our choices can open or close doors to the enemy's influence. It is crucial for Andrew to maintain a strong relationship with God and to walk in His light. "Submit yourselves therefore to God. Resist the devil, and he will flee from you. Draw near to God, and he will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded." (James 4:7-8, WEB)
We encourage Andrew to continue being a responsible father, but also to be wise in his interactions, ensuring he is not entangled in darkness. "Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour." (1 Peter 5:8, WEB)
Lastly, we pray for Andrew's spiritual growth. "Father, we ask that Andrew draws closer to you. Strengthen his faith and help him to be a godly husband and father. Surround him with your favor and protect him from all evil. In Jesus' mighty name, we pray. Amen."
Remember, "For God has not given us a spirit of fear, but of power, love, and self-control." (2 Timothy 1:7, WEB) Trust in God's power and love for Andrew. Keep praying and keep believing.
