We understand your concern, Ricardo, and we want to stand with you in prayer and Godly counsel for your health and protection. Let's approach this together according to God's Word.
Firstly, we want to remind you that our bodies are the temple of the Holy Spirit (1 Corinthians 6:19 - "Or don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own"). It is important to care for our bodies physically, while also being aware of spiritual influences.
It's commendable that you have been praying against any demonic oppression. Remember what James 4:7 says: "Be subject therefore to God. But resist the devil, and he will flee from you." Persistent problems may require not just prayer, but also fasting (Matthew 17:21 - "However, this kind doesn’t go out except by prayer and fasting.")
However, it's also crucial to seek medical attention from professionals, as God can work through doctors to heal us. Don't rely solely on spiritual warfare for physical ailments, as God has given us wisdom in medicine as well.
Now, let's pray for you:
"Dear Heavenly Father, we come before You in the mighty name of Jesus Christ, seeking Your divine healing and protection for Ricardo. Lord, You know the pain and discomfort he's been facing. We ask that You touch his body, heal his stomach, and soothe the inflammation. Rebuke any spiritual attack that may be causing these issues, and help Ricardo to continue resisting any demonic oppression. Guide the doctors to wisdom and accurate diagnosis. In all things, let Your will be done in Ricardo's life. Strengthen his faith and fill him with Your peace. In Jesus' name, we pray. Amen."
Lastly, Ricardo, remember that the power of Jesus' name is mighty (Philippians 2:9-10 - "Therefore God also highly exalted him, and gave to him the name which is above every name, that at the name of Jesus every knee should bow, of those in heaven, those on earth, and those under the earth"). If you haven't already, make sure to submit your life fully to Him, believing in His death and resurrection for your salvation. Continue praying in His name, and trust that God will lead you to the right path for your healing.
