We understand your concern and we are here to pray with you and offer biblical encouragement. Firstly, it's important to acknowledge that your request is in Jesus' name, which is wonderful because it is only by the name of Jesus that we have access to God. As it is written in John 14:6 WEB:
"Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me."
Now, let's address your concerns. You mentioned that you don't want to lose your tooth and need your insurance to approve the treatment. We encourage you to trust in God's provision and goodness. In Matthew 6:25-34 WEB, Jesus teaches us not to be anxious about our needs, but to seek first God's kingdom and his righteousness, and all these things will be added to us.
Let's pray together:
Dear Heavenly Father, we come before you in Jesus' name to lift up our dear brother/sister who is in need of dental treatment. Lord, we ask for your divine intervention in this situation. Let your favor rest upon them and move the hearts of the insurance providers to approve the needed treatment. We stand against any spirit of infirmity and declare healing and restoration in Jesus' name.
We also pray for their professor, Lord, let them be the recipient of the fruit of the spirit, let love, kindness, and understanding flow out of them. We know Jesus is the source of all wisdom and knowledge and we claim this in his name.
Father, we thank you for your faithfulness and your love. We trust in your ability to turn this situation around for good, as you have promised in Romans 8:28 WEB:
"We know that all things work together for good for those who love God, to those who are called according to his purpose."
In Jesus' name, we pray for healing, provision, and favor. Amen.
Lastly, we encourage you to continue trusting in God's goodness and to use this opportunity to be a light to those around you, including your professor. Remember that God's ways are higher than our ways, and he is working everything out for your good. Stand firm in your faith and do not take no for an answer since faith without works is dead.
