We understand that you're concerned about your son's truck and the financial burden he's facing. Firstly, we appreciate that you acknowledged the power of Jesus' name, as it is only through Him that we have access to God.
Let's pray together:
"Father, we come before You in Jesus' name, lifting up our brother who is in need. We ask that You would provide for him in this time of financial strain, as his truck's transmission has failed and he's facing a costly repair. We pray for Your guidance and wisdom, that You would direct him to a reliable and affordable solution. We ask that You would help him in this time of need. In Jesus' name, we pray. Amen."
We also encourage your son to trust in God's provision and timing. It's important to remember that God cares for us and knows our needs. As it says in Matthew 6:25-34 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? Which of you, by being anxious, can add one moment to his lifespan? Why are you anxious about clothing? Consider the lilies of the field, how they grow. They don't toil, neither do they spin, yet I tell you that even Solomon in all his glory was not dressed like one of these. But if God so clothes the grass of the field, which today exists, and tomorrow is thrown into the oven, won't he much more clothe you, you of little faith? Therefore don't be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?' For the Gentiles seek after all these things, for your heavenly Father knows that you need all these things. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well. Therefore don't be anxious for tomorrow, for tomorrow will be anxious for itself. Each day's own evil is sufficient."
Lastly, we would like to remind your son to continue to be a good steward of the resources God has entrusted to him, and to use this situation as an opportunity to grow in faith and dependence on God.
