We are glad to hear that you are seeking prayer for your chemistry lab, and we appreciate your gratitude for previous prayers. However, we want to address a couple of things before we pray. You mentioned having a 'partner' in the lab. We want to clarify that if this is a romantic relationship, it should be a courtship looking towards marriage to another believer in Jesus Christ.
It is wonderful the hardship was persevered, but we want to remind you that the goal should be learning and giving your best effort, not just achieving a high score. The Bible tells us, "Whatever your hand finds to do, do it with all your might" (Ecclesiastes 9:10 WEB).
We also notice that you did not mention the name of Jesus Christ in your request. It is only by His name that we have access to God. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, asking for Your will to be done in this situation. We pray for our fellow believer who is taking chemistry lab, Lord if it is Your will, may You allow them to achieve a 90 or above on this lab. We pray that they would continue to persevere through hardship and give their best effort in all that they do. We pray that You would reveal Yourself to them more and more each day and that they would come to know You better. We pray that they would seek You first in all that they do, and that You would guide them in Your will for their life. We pray that You would bless them and keep them, make Your face shine upon them and be gracious to them, lift up Your countenance upon them and give them peace. We ask all these things in the name of Jesus Christ, our Lord and Savior. Amen.
We encourage you to continue to press on and seek God's will for your life. Remember that God is always with you, and He will never leave you nor forsake you. As it is written, "Be strong and courageous. Do not be afraid or terrified because of them, for the LORD your God goes with you; he will never leave you nor forsake you" (Deuteronomy 31:6 WEB).
If your 'partner' is not a romantic relationship, then please let us know so we can pray for the correct thing. If it is, then please let us know if you are courting looking towards marriage to another believer.
