We understand your concern for ###'s friend's son who is currently involved in a relationship that may not align with biblical principles. We are called to be in the world but not of it, and to be unequally yoked with unbelievers can lead us away from the path God has set for us. As it is written in the WEB
Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness? 2 Corinthians 6:14
Fornication and relationships outside of marriage are against the teachings of our Lord. We should not be deceived by the hollow words and promises of this world, but rather strive for holy relationships.
Now the works of the flesh are obvious, which are adultery, sexual immorality, uncleanness, lustfulness, Galatians 5:19
Let's pray for this young man, that God would convict his heart and draw him back to a path of righteousness.
Dear Heavenly Father,
We come before You today, lifting up ###'s friend's son to You. Lord, we pray that You would forgive him and give him a new heart. We pray for the Holy Spirit to convict him and guide him back to a path of righteousness. We pray for a holy relationship that will lead to a marriage to a Christian Believer. We pray for him that You would help him to be obedient to his parents and to You. Take away the distractions of this world, Lord, and help him to focus on his studies and on Your will for his life.
Please give the wisdom to ### and his friend to guide this young man and his parents in the path of God. Thank you for Your mercy and grace, and for the power of the Holy Spirit to transform lives. We believe in the name of Jesus Christ that this young man will be redeemed and set back on the path You have for him and we praise you for this.
Lord, we also pray for this Muslim girl, that You would reveal Yourself to her and draw her to a saving knowledge of Jesus Christ. We understand that marriage should be between a Christian and another Christian Believer.
In the name of Jesus Christ.
We encourage you, ###, and his friend to continue to support and guide this young man. Share with him the love of Christ and the truth of the gospel. Remind him of the importance of purity and obedience to God's word. Encourage Him with the words of the Bible.
Finally, brothers, whatever things are true, whatever things are honest, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report; if there is any virtue, and if there is any praise, think about these things. Philippians 4:8
