We are glad to join with you in prayer for your daughter as she prepares for her GCSE exams. Firstly, let us remember that God is the source of all wisdom and knowledge. Proverbs 2:6 WEB tells us, "For Yahweh gives wisdom. Out of his mouth comes knowledge and understanding."
In all things we ask, it is important to ask in the name of Jesus. It is only by the name of Jesus that we can come to the Father in prayer. John 14:13 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son." It is also important to believe that Jesus is the only way to God the Father. 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."
Let us pray together:
"Dear Heavenly Father,
We come before You in the name of Jesus, lifting up our daughter who is preparing for her GCSE exams. We ask that You would grant her the wisdom, knowledge, and understanding she needs to succeed. Help her to stay focused, calm, and confident in her abilities. Guide her as she studies and help her to be the best she can be.
We ask this in Jesus Christ's name. It is only in the name of Jesus that we can come to God the Father in prayer.
Amen."
May this time also be an opportunity for your daughter to draw closer to God and see His faithfulness in her life. Encourage her to trust in the Lord with all her heart, and lean not on her own understanding. In all her ways, let her acknowledge Him, and He will make her paths straight. Our thoughts and prayers are with you and your daughter during this important time.
