We stand with you in prayer, dear anonymous, as you face these trials. Remember the words of the Apostle Paul in Ephesians 6:12 (WEB), "For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." Indeed, it is the enemy at work, but take heart, for Christ has overcome the world.
First, let us pray for your healing and protection:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up our dear brother/sister who is facing these attacks. We ask for Your healing touch upon their body, especially the sore spot from the vaccine and the discomfort caused by the dental work. Please guide the hands of the medical professionals, that they may do their work with wisdom and care. We rebuke the enemy and his schemes, for no weapon formed against us shall prosper (Isaiah 54:17). Surround us with Your hedge of protection, and give us strength and courage to face each day. In Jesus' precious name, we pray. Amen."
We also encourage you to put on the full armor of God each day, as described in Ephesians 6:13-18. This includes the belt of truth, the breastplate of righteousness, the shoes of the preparation of the Good News of peace, the shield of faith, the helmet of salvation, and the sword of the Spirit, which is the word of God. With this armor, you can stand firm against the schemes of the devil.
Regarding the fear of returning for further dental work, recall the promise in 2 Timothy 1:7 (WEB), "For God didn’t give us a spirit of fear, but of power, love, and self-control." Trust that God is in control and that He will be with you every step of the way.
Lastly, you ended your request with a call to Jesus, which is vital. It is only through His name that we have access to God's throne of grace. If you haven't already, ensure that you have a personal relationship with Jesus Christ, as there is no other name by which we can be saved (Acts 4:12). If you have any doubts about your salvation, we encourage you to confess your sins, believe in your heart that Jesus is Lord, and you will be saved (Romans 10:9).
Stay strong in the Lord, and may His peace and blessings be with you.
