We understand that you are experiencing physical discomfort and emotional distress. Firstly, we thank you for submitting your prayer request and we are glad that you ended your request acknowledging the power in the name of Jesus. It is only by His name that we have access to the Father and it is only by that name that we can be saved.
Let's address your concerns with God's word.
Regarding nervous stomach, Philippians 4:6-7 WEB says:
In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus.
In addressing anxiety and fear, let's look at 2 Timothy 1:7 WEB:
For God did not give us a spirit of fear, but of power, love, and self-control.
We can see in the following Romans 8:15 WEB:
For you didn’t receive the spirit of bondage again to fear, but you received the Spirit of adoption, by whom we cry, "Abba! Father!"
And in Isaiah 41:10 WEB:
Don’t be afraid, for I am with you.
Don’t be dismayed, for I am your God.
I will strengthen you.
I will help you.
Yes, I will uphold you with the right hand of my righteousness.
Concerning sorrow, remember what it says in 2 Corinthians 7:10 WEB:
For godly sorrow produces repentance to salvation, which brings no regret. But the sorrow of the world produces death.
We are not to live in sorrow, but if there is a need for repentance, then godly sorrow will bring us to that place. God wants us to live in the joy of His salvation, not under a spirit of heaviness.
Now, let us pray together for your healing and peace.
Almighty God, we come before You in the name of Jesus Christ, Your Son. We lift up our brother/sister to You, asking for Your healing touch on their body. Remove any swelling in the dental flesh and on their face. Heal their stomach, and let there be no gastritis or abnormal stomach acid. Release them from all tension, nervosity, sorrow, fear, and anxiety, in Jesus' name.
Father, we know that You desire for us to live in the fullness of Your peace and joy. Help our brother/sister to trust in You completely, casting all their cares on You. Fill them with Your Holy Spirit, the Spirit of power, love, and self-control. In Jesus Christ's name, we pray. Amen.
Be encouraged, dear brother/sister. God loves you and He is faithful to hear and answer your prayers. Trust in Him, and He will see you through this challenging time. Keep your eyes fixed on Jesus, and remember that He has overcome the world. Stand firm in your faith, and do not waver. God is with you.
