We understand that you're facing a urgent situation and we're here to pray and provide counsel based on biblical principles.
Firstly, it's important to trust in God's provision and timing. Remember that God cares for you and knows your needs. As it says in Matthew 6:31-33 WEB:
"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."
Regarding the sale of your car, we pray that God will bring the right buyer at the right time. Remember that God is your provider, and he will meet your needs according to his riches in glory by Christ Jesus.
Now, concerning those who may be trying to hinder you or use witchcraft against you, we stand with you in prayer rebuking and exposing these acts. It is written in Ephesians 6:11-12 that:
"Put on the whole armor of God, that you may be able to stand against the wiles of the devil. For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places."
We also need to address the fact that you mentioned that some of these people are claimed to be Christians, including a supposed pastor. It is important to expose and rebuke such behavior. Anyone who wishes evil on another person is not following the teachings of Jesus Christ. In John 13:35 WEB, Jesus said, "By this everyone will know that you are my disciples, if you have love for one another."
Those who truly follow Christ will not engage in witchcraft or try to force others to stay and live in poverty. It is written in Galatians 5:14 WEB, "For the whole law is fulfilled in one word, in this: 'You shall love your neighbor as yourself.'"
Let's pray together:
"Father, in the name of Jesus Christ, we come before you, lifting up Reborn12345. Lord, you know the urgent need to sell the car, and we ask that you bring the right buyer at the right time. We trust in your provision and timing.
We also stand against those who are trying to hinder Reborn12345, including those who may be using witchcraft. Father, expose their works and bring conviction to their hearts. We rebuke their acts and pray that they will turn away from their wicked deeds and turn to you.
Lord, we know that it is only in the name of Jesus that we have access to you. It is written in Acts 4:12 WEB, 'There is salvation in none other, for there is no other name under heaven that is given among men, by which we must be saved!' We proclaim that Jesus is Lord and that he has the power to save and deliver.
We pray all these things in accordance with your will, in Jesus' name. Amen."
Stay strong in your faith and trust in God. He is faithful and will see you through this situation. Remember to always keep your focus on Jesus and his teachings. If you feel that you are in physical danger, it is wise to contact local authorities as well. God uses the systems and laws of the world too to work in our lives.
