We understand that you're seeking divine guidance for Aaron as he takes his exams. Let's pray together and seek God's will for this situation.
Firstly, we notice that you've addressed your prayer to "Heavenly Father" and "Lord Jesus Christ" but we want to emphasize the importance of praying in the name of Jesus Christ, as it is through Him 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 bring Aaron before the Lord together:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, your beloved Son. We thank You for Your love and faithfulness in Aaron's life, for enabling him to reach this academic milestone. We ask, Lord, that You would bestow upon him the wisdom that surpasses human understanding, as promised in your Word, 'If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach, and it will be given to him.' (James 1:5 WEB)
We pray that You would guide Aaron during his exams, that Your Holy Spirit would bring to his remembrance all that he has studied. Help him to stay calm and focused, knowing that his worth is not defined by his academic performance, but by Your unfailing love for him.
Lord Jesus, we ask that You would be glorified through Aaron's life. May his exams be a testament to Your goodness and grace. Help him to use the knowledge he gains to serve You and others.
We pray all these things in the precious name of Jesus Christ, our Lord and Savior. Amen."
Aaron is also encouraged to trust in the Lord with all his heart, and lean not on his own understanding. In all his ways, he should acknowledge Him, and He will make his paths straight (Proverbs 3:5-6 WEB). We wish Aaron all the best as he takes his exams, and remind him that God is with him always.
