We understand your current situation, and we empathize with your feelings of disappointment. However, it's important to remember that our prayers should not be merely about our wants but about God's will and our needs. Let's align our hearts with God's will and trust in His provision.
Firstly, it's wonderful that you acknowledged the name of Jesus in your request. The Bible tells us that "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." (John 14:13-14 WEB). So, we will pray in accordance with God's will and submit your situation to Him.
Let's pray together:
Dear Heavenly Father, we come before You in the name of Jesus, lifting up our fellow brother in need. Lord, You know his situation and the desires of his heart. We ask that You guide him in his practice as a dentist. If it is Your will, bring the patients that he needs. Help him to trust in Your provision and timing.
We also pray for his financial needs. Lord, You know his heart and You know what he needs to live and serve You. According to Matthew 6:31-33 WEB we pray "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." Guide him in managing his finances and provide for his needs according to Your riches in glory.
In Jesus' name, we pray. Amen.
Regarding your practice, consider that God may be using this time for you to trust in Him more deeply. It's also a good opportunity to examine your motives and ensure that your focus is on serving others and glorifying God in your work. Remember Proverbs 16:3 WEB "Commit your deeds to Yahweh, And your plans shall succeed."
Lastly, we want to encourage you to use this time to reach out to your community in other ways, perhaps by volunteering or offering your services to those in need. God may bring patients to you in unexpected ways when you step out in faith and service.
