We understand your concern for your friend's situation, and we're here to support you in prayer and counsel. Firstly, it's important to remember what the WEB says in Galatians 6:1, "Brothers, even if a man is caught in some fault, you who are spiritual must restore such a one in a spirit of gentleness; looking to yourself so that you also aren't tempted."
Addressing sin in a loved one's life can be challenging, but it's essential to do so with love, gentleness, and humility. Ensure that your approach is not judgmental but rather filled with care and a genuine desire to see them grow and change. Also, consider the words of Jesus in Matthew 7:3-5, "Why do you see the speck that is in your brother’s eye, but don’t consider the beam that is in your own eye? Or how will you tell your brother, 'Let me remove the speck from your eye,' and behold, a beam is in your own eye? You hypocrite! First remove the beam out of your own eye, and then you can see clearly to remove the speck out of your brother’s eye."
Before addressing the sin in your friend's life, make sure to examine your own life and repent of any wrongdoing. Then, guided by the Holy Spirit, approach your friend with love and patience.
Now, let's pray together:
"Dear Heavenly Father, we come before You today in the name of Jesus Christ. We lift up our friend to You, Lord. We ask that You open their eyes to see the areas in their life that are not pleasing to You. Grant them a heart of repentance and a desire to turn away from sin.
Lord, we also seek Your guidance for Rocshath. Give them the wisdom to know how to approach their friend, the courage to speak the truth in love, and the gentleness to reflect Your heart. Help them to be a positive influence and a light that points to You.
We know that it is only through the name of Jesus Christ that we have access to You, Father. And it is in His name that we pray, believing that we are saved by grace through faith in Him alone. Amen."
Remember, Rocshath, it is the kindness of God that leads to repentance (Romans 2:4). As you intervene in your friend's life, be a vessel of that kindness, and trust God for the outcome.
