We are truly saddened to hear about the painful situation you're facing, ###. In times like these, it's crucial to turn to God's word for guidance and comfort. We will pray with you, but we also want to address this situation in light of biblical principles.
Firstly, it's important to understand that God desires holy and pure relationships. He warns us, "Do not be deceived. Evil companionships corrupt good morals." (1 Corinthians 15:33 WEB) The man your girlfriend is with has led her into a destructive lifestyle of drugs and immorality, which is not God's will for her or anyone.
We should indeed pray for her safety and that God would deliver her from this harmful situation. But more importantly, we should pray that she turns her heart towards God, repents, and seeks His will for her life. God promises, "If we confess our sins, he is faithful and righteous to forgive us the sins, and cleanse us from all unrighteousness." (1 John 1:9 WEB)
However, we must also address that it's not our place to pray for her to come back to you, but rather to pray for God's will to be done in both of your lives. If she is not committed to a life with Christ, it is not wise to pursue a relationship with her. The Bible warns, "Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?" (2 Corinthians 6:14 WEB)
Let's pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up ### and his girlfriend to You. Lord, we ask that You would deliver her from the destructive path she's on, that You would open her eyes to the truth of her situation, and draw her heart to You. Please protect her from harm and give her the strength to break free from the bonds of drugs and immorality.
Lord, we also pray for ###. We ask that You would heal his broken heart, give him peace that passes all understanding, and help him to trust in Your plan for his life. Help him to seek You first and to desire a godly spouse who loves and serves You.
In Jesus' name, we pray. Amen."
###, remember that God loves you deeply and has a good plan for your life. Trust in Him, and He will guide your paths. "Trust in the LORD 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." (Proverbs 3:5-6 WEB)
Prayer Focus: God, Thank You for loving me. Thank You for loving me, Jesus. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have. Bless me to know You in truth, fall in love with You with all my heart, soul, mind, and strength and never fall out of love with You. Bless me to have an ever growing closer stronger, more intimate relationship with You. Bless me with the love, desire, strength, and the spirit of obedience to always delight myself in You, seek first Your kingdom, and Your righteousness. Help and strengthen me God to always respect and obey You. Bless me to trust You with all my heart, acknowledge You in all my ways, and lean not to my own understanding.
