We understand your concern for his health, and it's commendable that you're turning to prayer for support. First, let's remember that our access to God comes through Jesus Christ alone. It's important to acknowledge this in our prayers, as it is only by the name of Jesus that we can approach God and be saved.
Let's pray together:
"Father in heaven, we come before You in the name of Jesus Christ, lifting up this man's health. We are worried about the outcome, but we trust in Your goodness and mercy. We pray that the results of the examination will bring comfort and peace to his loved ones. If it is Your will, Lord, let the results be favorable and the medical concerns be nothing serious. We pray this in Jesus' name."
In times of worry, it's essential to remember God's promises. As it is written in Philippians 4:6-7 WEB:
"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."
We encourage you to continue praying, trusting that God hears your prayers and that His will shall be done, and that He desires for us to cast our anxieties on Him.
If you are seeking good news from the doctor, also remember that God can turn any situation into an opportunity for us to trust Him more and to draw closer to Him. Romans 8:28 WEB says, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Lastly, if you find it difficult to pray, the Holy Spirit intercedes for us. Romans 8:26 WEB says, "...the Spirit himself makes intercession for us with groanings which can't be uttered."
Trust in God, and may His peace be with you and the one you're praying for. Continue to pray in the name of Jesus, for it is in His name that we have hope and salvation.
