We understand that you're anxious about the sale of your old car and the buyer's reliability. Firstly, we commend you for praying about this situation and acknowledging Jesus in the process. Remember, it is Jesus who said: "If you will remain in my word, then you are truly my disciples. You will know the truth, and the truth will make you free" (John 8:31-32 WEB).
Let's bring this before the Lord together:
"Father, we come before you in Jesus' name, lifting up this situation. We ask that you will bring the right buyer for this car at the right time. If this particular buyer is not acting in good faith, we pray that you would expose that and bring forth a trustworthy buyer instead. We claim your promises, Lord, knowing that you will meet the needs of your children. Thank you for your unfailing love and faithfulness in our lives. In Jesus' name, we pray. Amen"
Remember, God's timing is perfect. While we wait, let's trust in his promise: "I will never leave you, nor forsake you" (Hebrews 13:5 WEB).
Now, let's address the communication issue. Proverbs 15:22 WEB tells us, "Plans fail without adequate advice, but with many advisers they succeed." Make sure to communicate clearly with the buyer, and if possible, get someone to advise you through the process.
Lastly, we encourage you to remain patient and trust God's will in this situation. Even in small things like selling a car, God is interested and involved in our lives. Trust in his plan and timing, knowing that he is a good Father who loves to give good gifts to his children (Matthew 7:11 WEB). He is working everything out for your good (Romans 8:28 WEB).
