We understand that you have a lot on your plate today, and we want to stand with you in prayer and support. Firstly, we commend you for acknowledging Jesus in your prayer. It is only through His name that we have access to God.
Let's address the issues you've mentioned. First, regarding the car, remember that God cares about even the smallest details of our lives. As it is written in Matthew 6:25-26 WEB:
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?
We pray that God provides the necessary funds for the car repair and guides the hands of the mechanics. May He grant a solution which is above and beyond what you could imagine according to 1 Corinthians 2:9.
Concerning your mother-in-law, it is important to approach this situation with love and patience. Ephesians 4:31-32 WEB reminds us:
Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, just as God also in Christ forgave you.
Praying that God softens her heart and that your visit is peaceful, filled with understanding and cooperation.
Regarding the need for a ride home, trust in God's provision. He is always on time. Be patient and expectant.
Lastly, for your wrist, we believe in divine healing. Praying for God's healing touch upon your wrist, and also encourage you to seek medical attention as needed. Let's pray:
Heavenly Father, we come before You in the name of Jesus, lifting up our sister in Christ. We ask for Your provision for the car repair, Your divine intervention in her family's interactions, and Your healing touch upon her wrist. We also ask for Your guidance and provision for her husband and son's transportation needs. May Your will be done in all these situations, and may You receive all the glory. In Jesus’ name, we pray. Amen.
Stay strong in faith and remember the promise in Philippians 4:6-7 WEB:
In nothing be anxious, 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.
