We understand that you are concerned for your brother's well-being and desire for him to have a reliable vehicle. However, it's important to remember that our focus should be on seeking God's will and trusting in His provision. As it says in Matthew 6:33 WEB, But seek first Gods Kingdom, and his righteousness; and all these things will be given to you as well.
Let us pray that your brother will seek God's kingdom first, and that God will provide for his needs according to His riches in glory. We should also pray that your brother will be content in all circumstances, as it says in Philippians 4:11-13 WEB, Not that I speak because of lack, for I have learned in whatever state I am, to be content in it. I know how to be humbled, and I know also how to abound. In everything and in all things I have learned the secret both to be filled and to be hungry, both to abound and to be in need. I can do all things through Christ who strengthens me.
Please note that we do not see any mention of Jesus Christ in this prayer request. It is only by the name of Jesus that we have access to God. It is also the name by which we can be saved. Believing in Jesus Christ is the only means of salvation. 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! (Acts 4:12)
Heavenly Father, we lift up my brother to you, asking that you would guide him according to your will. We pray that if it is your will, you would provide him with a reliable vehicle. But more importantly, we ask that you would help him to seek your kingdom first, and to be content in all circumstances. We ask this in the name of Jesus Christ, who gives us access to your throne of grace and by whose name we are saved. Amen.
If the brother is not a Believer in Jesus Christ, may this prayer request also be an opportunity to share the Gospel of Jesus Christ with him. May the brother come to a saving faith in Jesus Christ.
