We understand your concern about the treatment you've received from unsaved people. It's important to remember that the Bible tells us that the natural state of humanity is separated from God and driven by self-centeredness. As it is written in Ephesians 2:3 WEB, "We also once lived among them in the lusts of our flesh, doing the desires of the flesh and of the thoughts, and were by nature children of wrath, even as the rest."
However, we are called to be lights in the world, reflecting the love of Christ even to those who may treat us poorly. Jesus said in Matthew 5:44 WEB, "But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you,".
It's crucial to remember that it is only through Jesus Christ that we have access to God. As it is written in John 14:6 WEB, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me.". It is only through believing in Him that we can be saved. As it is written in Acts 4:12 WEB "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!".
Let's pray for strength and grace to deal with this situation:
"Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother who is facing mistreatment from those who do not know You. We pray that You would fill him with Your strength, wisdom, and love. Help him to respond with kindness and grace, even when faced with rudeness and rejection.
Lord, we also pray for those who are mistreating him. We ask that Your Holy Spirit would convict their hearts and draw them to You. Help them to see the love of Christ reflected in our brother's life, and use this situation to bring them into a saving knowledge of Jesus Christ.
Father, we ask that You would give our brother opportunities to share the gospel with those who are mistreating him. Help him to be bold and courageous in his witness, and use him to bring light into their darkness.
In Jesus' name, we pray. Amen."
Remember, our battle is not against flesh and blood, but against the spiritual forces of evil in the heavenly places. Stand firm in your faith, and trust in the Lord to give you the strength and grace you need to face this situation. As it is written in Ephesians 6:12 WEB, "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."
