We understand your pain and heartache, dear friend, but we must guide you according to the principles laid out in God's Word. Firstly, let's address the issue of the relationship itself. In 2 Corinthians 6:14, WEB, it is written, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" If your ex-fiancé is seeking to reconcile with his former wife, it suggests that they are not aligned with God's will, as divorce is not God's intention except in specific cases of infidelity (Matthew 19:9, WEB).
Moreover, it's crucial to understand that trying to win him back, especially when he is attempting to reconcile with his former spouse, may not be God's best for you. In Jeremiah 29:11, WEB, God says, "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." Trust that God has a plan for your life and your relationships.
We must also address the language used in your request. The term "bullsh**" is not appropriate and goes against Ephesians 4:29, WEB, which states, "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."
Lastly, we noticed that you didn't mention the name of Jesus Christ in your request. It's essential to understand that it is only through Jesus that we can approach God. In John 14:6, WEB, Jesus says, "I am the way, the truth, and the life. No one comes to the Father, except through me."
Let us pray for you:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We lift up our dear sister who is hurting right now. Lord, we ask that You comfort her heart and help her to trust in Your plan for her life. Guide her steps and lead her to a godly spouse if it is Your will. Help her to let go of the past and move forward in Your grace and love. In Jesus' name, we pray. Amen."
We encourage you to seek God's will in this situation and trust that He has the best plan for your life.
