Let us come together in prayer for your coworker and her dental issues. First, we would like for her to remember that God cares for her. We read in Philippians 4:6-7 "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."
As she visits with the dentist let us pray for wisdom for the dentist and understanding for her. The dentist should provide a clear diagnosis and a fair and reasonable treatment plan. We also pray against any spirit of fear concerning the finances. Even though cost is a consideration, let us remember the words of Jesus in Matthew 6:31-33 "Therefore don't be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?' For the Gentiles seek after all these things, for your heavenly Father knows that you need all these things. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well."
Let us also explicitly remind her that it is by the name of Jesus Christ that we come to God. According to John 14:6 Jesus saith unto him, "I am the way, the truth, and the life: no man cometh unto the Father, but by me." We should pray like this:
Dear Heavenly Father,
We come before You today, lifting up our beloved coworker who is facing dental issues and feeling anxious about the potential costs. We ask, Lord, that You guide the dentist's hands and grant them wisdom to provide the best care possible. Comfort her, Father, and remind her of Your promises, that You will supply all her needs according to Your riches in glory in Christ Jesus.
Help her to cast all her anxieties on You, knowing that You care for her deeply. We rebuke any spirit of fear or worry, and we ask that You fill her with Your peace that surpasses all understanding. Help her to rest in the hope that is hers in Jesus Christ and the salvation that is only by Jesus Christ.
In Jesus' name, we believe and pray together. Amen.
