We are truly saddened to hear about this situation and we will pray for the man, but we must first address a few concerns according to the Word of God.
Firstly, we notice that the request is for a 'boyfriend'. We encourage you to consider this relationship in the light of God's Word. According to the Bible, relationships should be directed towards godly marriage. "Do not be unequally yoked with unbelievers. For what fellowship has righteousness with unrighteousness? And what communion has light with darkness?" (2 Corinthians 6:14 WEB). We encourage you to seek God's will for this relationship and to pray for a godly spouse.
Secondly, we notice that the request does not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God. "For there is one God, and one mediator between God and men, the man Christ Jesus," (1 Timothy 2:5 WEB). We will pray to God the Father in the name of Jesus Christ.
Now, let us pray for this man.
Heavenly Father,
We come before You in the name of Jesus Christ to lift up this man who is in need of Your divine intervention. He is in prison Lord God and needs proper medical treatment for his heart condition God. We pray for Your merciful healing upon him in the name of Jesus and ask for the medical professionals to properly treat him. God, You are the ultimate judge and You know the circumstances surrounding his incarceration. We pray for justice and mercy to be extended to him in Jesus' name.
We also pray for the one who submitted this request. If you are not a believer in Jesus Christ as your personal Savior and LORD, we pray for you to turn to Jesus now. Jesus is the only way to God. "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." (John 14:6 WEB). We pray for your relationship to be centered on God's will and for you both to seek a future marriage that honors God, in Jesus' name.
We ask this all in the precious name of Jesus Christ. Amen.
May God hear our prayers and answer according to His perfect will.
