We understand your heartache, but first let's reaffirm our relationship with God. It's wonderful that you ended your prayer "In your name I pray, Amen," but we want to ensure you're praying in the name of Jesus Christ. It's only through Jesus that we have access to God, as it's written, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
Now, let's address your situation. You've acknowledged that you were not a good man and that your ex-girlfriend had good reasons to leave. This is a start, but let's remember the biblical perspective on relationships. God's will is for us to be holy, to stay away from sexual immorality and fornication. In God's eyes marriage is a sacred union between a man and a woman to avoid sexual immorality. This is why we need to seek a spouse rather than a girlfriend. If you were involved in sexual immorality, take this time to repent and turn away from this sin.
It's also important to understand that God does not always grant our requests in the way we expect. Instead of praying for your ex-girlfriend to return, focus on seeking God's will for your life and becoming the man He wants you to be. "Trust in Yahweh 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).
Let's pray together:
Dear Lord Jesus, we come before You, acknowledging that You are the only way to the Father. We repent for past sins and ask for Your forgiveness. Lord, we ask that You help this individual to become the man You want him to be. Guide him in Your will, and if it's according to Your plan, reunite him with his former companion, this time in a godly courtship as they both grow closer to You.
Help him to trust in You and Your timing. We pray In Jesus Name. God, we praise You for You are good, and Your love endures forever. Amen.
Be encouraged by these words from the Psalms: "Delight yourself also in Yahweh, and he will give you the desires of your heart. Commit your way to Yahweh. Trust also in him, and he will do this" (Psalm 37:4-5 WEB). Keep delighting yourself in the Lord, and He will give you the desires of your heart—desires that align with His will.
