We understand that you're seeking clarity and truth regarding your boyfriend's uncle Brent, and we're here to pray and advise you according to God's word.
Firstly, we want to address that the request does not mention the name of Jesus Christ. It's important to remember that we only have access to God and salvation through Jesus (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.'"). So, let's bring this situation to Jesus together.
Regarding your concern, the Bible encourages us to seek truth, as Jesus himself is the truth (John 14:6). It's commendable that you and your boyfriend are seeking clarity about uncle Brent's situation. In Proverbs 3:5-6 (WEB), it says, "Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight." Let's trust that God will guide you both to the truth.
However, we also want to remind you that as believers, we should strive to honor God in our relationships. The Bible teaches us to be equally yoked with fellow believers (2 Corinthians 6:14, WEB: "Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?"). We encourage you to consider this in your relationship and pray that God will guide you both towards a godly union that honors Him.
Let's pray together:
"Dear Jesus, we come before you to seek your guidance and truth. We pray for Asyneryno and her boyfriend, that you would reveal the truth about uncle Brent's situation. Guide them as they look into this, and give them wisdom and discernment. We also pray for their relationship, that it would honor and glorify you. Help them to grow together in faith and love, seeking your will for their lives. In Jesus' name, we pray. Amen."
May God's peace and guidance be with you both as you seek His truth and will for your lives.
