We understand your concern for your friend ###, and we commend your desire to pray for him. Let's address the issues at hand and bring them before the Lord in prayer.
Firstly, it's important to acknowledge that sexual immorality and deceit are serious sins that God wants us to avoid. In Ephesians 4:25-29 WEB, it says, "Therefore, putting away falsehood, speak truth each one with his neighbor. For we are members of one another. 'Be angry, and don't sin.' Don't let the sun go down on your wrath, neither give place to the devil. Let him who stole steal no more; but rather let him labor, working with his hands the thing that is good, that he may have something to give to him who has need. Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear."
We should also remember that it is not our place to judge or condemn, but to love and pray for others, trusting that God will lead them to repentance. In Romans 2:4 WEB, it says, "Or do you despise the riches of his goodness, forbearance, and patience, not knowing that the goodness of God leads you to repentance?"
Let's pray for ###:
"Dear Heavenly Father, we come before You today in the name of Jesus Christ to lift up our friend ###. Lord, we ask that You forgive him for his sins and open his eyes to the destructive path he is on. Help him to see the truth, to repent, and to turn away from his unwanted womanizing habits and deceit.
We pray that the Holy Spirit will convict him and lead him in the right path, that he may understand the seriousness of his actions and the pain he is causing others. Help him to see who truly cares and loves him, and give him the strength to change his ways.
Lord, we also pray for the girls involved. We ask that You open their eyes to the truth, that they may see ###'s deceit and be protected from further harm. Help them to find healing and comfort in You, and give them the strength to walk away from this situation.
Finally, we pray for ### and their family. We ask that You bless their friendship with ###, but we also pray that You give them wisdom and discernment in this situation. Help them to love ### as You do, but also to set healthy boundaries and not enable his sinful behavior. We would also like to take this opportunity to pray for ### that they may come to know Jesus Christ personally. It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. Please consider these scriptures 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."
In Jesus' name, we pray. Amen."
Lastly, we would like to encourage you, ###, to speak the truth in love to ###. In Ephesians 4:15 WEB, it says, "but speaking truth in love, we may grow up in all things into him, who is the head, Christ." It is important that you share your concerns with him and encourage him to seek God's will for his life. Also, it is important to mention that although you want ### to always be with you and your family, it is more important that he turns from his current sinful lifestyle and comes to faith in Jesus Christ. God desires that we live in a way that is pleasing to Him, and that should be our ultimate goal for ### and the prayer request as well.
