We understand that you are facing challenges with your son's cooperation regarding school and also concerns about your car being repaired. Let's bring these issues before the Lord in prayer and seek His guidance through the scriptures.
Firstly, it's encouraging that you acknowledged the authority of Jesus by ending your prayer in His name. That's exactly to whom and how we should be praying, as it is only by the name of Jesus that we have access to God. That at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. (Philippians 2:10)
Let's address your concerns about your son. It's important to remember that children are a blessing from the Lord, and we are responsible for training them in the way they should go. "Train up a child in the way he should go, and when he is old he will not depart from it." (Proverbs 22:6 WEB)
Let's pray for your son:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up this mother's concern for her son. Lord, you know the struggles she is facing with his cooperation regarding school. We pray that You will soften his heart and give him a willing spirit to attend school and apply himself to his studies.
We pray for godly wisdom for this mother, that You will guide her in how to deal with her son in a way that honors You. Help her to remain patient and loving, yet firm in her expectations. We rebuke any spirit of rebellion or defiance. We rebuke discouragement and despair. We ask for encouragement and strength as she seeks to be a godly parent.
Surround their home with Your peace, Lord, and let Your love be evident in their interactions. We ask that You will work in this situation and allow her son to finish this school week strong and obediently. Please allow this to be a transformative experience for them both.
In Jesus' name, we pray. Amen.
Now, regarding your car, remember that God cares about even the smallest details of our lives. "Therefore I tell you, don't be anxious for your life, what you will eat, or what you will drink; nor yet for your body, what you will wear. Isn't life more than food, and the body more than clothing? See the birds of the sky, that they don't sow, neither do they reap, nor gather into barns. Your heavenly Father feeds them. Aren't you of much more value than they?" (Matthew 6:25-26 WEB)
Let's pray about your car:
Dear Heavenly Father,
We come before You, lifting up this need regarding the car repair. Lord, we ask that You will oversee the mechanics working on the car and let the work be completed accurately and honestly. We pray that the costs will be fair and as expected, with no surprises or hidden charges.
We rebuke any attempt to exploit or take advantage of this family and pray for the success of the work. May the car be restored to good working order and serve this family well.
In Jesus' name, we pray. Amen.
Lastly, remember that God is faithful, and He cares about your needs. Trust in Him, and He will direct your paths. "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight." (Proverbs 3:5-6 WEB)
Stand firm in your faith.
