We understand that you're feeling anxious about your upcoming driver's test and we're here to support you in prayer and guidance. Firstly, let's remember to approach our Heavenly Father through the name of Jesus Christ.
Before we address the test, for Jesus said, "Most certainly, I tell you, unless a person is born again, he cannot understand God's Kingdom."(John 3:3) Jesus is the only way to truly understand as the Kingdom is in the Holy Spirit. Jesus also said, "I am the way, the truth, and the life. As John says in John 14:6 as well, 'No one comes to the Father, except through me.' In Acts 4:11, 12, it says, "This is the 'stone which was regarded as worthless by you, the builders, which has become the head of the corner.' There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Regarding your situation, it seems you're feeling worried and stressed. We need to remember to "Have no anxiety at all, 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." Philippians 4:6-7.
In Luke 12:25-26 Christ speaks about not worrying about anything, because, "Which of you by worrying can add a single hour to his life? If then you aren't able to do even a very little thing, why are you anxious for the rest?"
For the mistakes and anything that causes worry, the Word of God urges all to acknowledge their mistakes in 1 John 1:9 as it promises "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." So if worry is a mistake, then understanding that with the cleansing power of God, complete joy can be had because there is no condemnation to those who are seeking God as in Romans 8:1.
Feel free to use the following as your guide to express your concerns and sought guidance
Dear Heavenly Father,
I come before you today with thanksgiving and praise, that the testing does not need to bring anxiety. I come to your throne of grace boldly, seeking mercy and grace, as instructed in Hebrews 4:16. Please Lord, guide me and minister to me, both in the coming days and as I take my driver's test. As Philippians 4:13 says, "I can do all things through Christ who strengthens me."
I pray for your will, Lord. Please remove any anxiety and worry I have been relying upon rather than wholly trusting in you, Father. If it is in Your will allow me to pass the exam tomorrow so that I may be a license holder and be able to assist my family. "Your word is a lamp to my feet, and a light for my path." Psalm 119:105, show me how to righteously pass with wisdom and guidance as your Word speaks. Let me be your hands and feet.
I ask all these things in the precious name of Jesus Christ, my Lord, and Savior.
Amen.
