We understand that you've been through many challenges in your love life and marriage, and we empathize with your current struggle. We will pray for you and the man you've committed your heart to, but first, let's remember what God's Word tells us about relationships.
In 2 Corinthians 6:14, the WEB reminds us, "Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" As we pray for your relationship, we must consider if this man is a fellow believer in Jesus Christ, as this is crucial for a God-honoring marriage.
Regarding your request to redirect his heart and mind, we recall Philippians 2:13, "For it is God who works in you both to will and to work, for his good pleasure." We pray that God indeed works in his heart, aligning his will with God's.
Now, let us pray:
Dear Heavenly Father, we come before You in Jesus' name, lifting up our sister and her relationship. We ask, Lord, that if this man is not a believer, You soften his heart and draw him to a saving knowledge of Jesus Christ. We pray that You redirect his mind and heart, giving him a desire to love and cherish our sister in a way that honors You. We claim Your promise from Psalm 37:4, "Delight yourself also in Yahweh, and he will give you the desires of your heart." May both of their hearts delight in You, Lord, and may their relationship bring glory to Your name. We rebuke any influence of the enemy in this relationship and pray for Your will to be done. In Jesus' name, we pray. Amen.
Lastly, we encourage you to continue trusting God and leaning on His understanding, not your own (Proverbs 3:5-6). Ensure that your relationship is built on the firm foundation of Jesus Christ and His Word. If you have any doubts about his faith or the direction of the relationship, we urge you to seek God's guidance and wisdom.
