We understand your urgency and desire for unity in your marriage. It's commendable that you're seeking God's intervention and praying for your husband's salvation. However, we need to address a few things in your request.
Firstly, we need to clarify that while we should pray for others, we cannot force someone to become a born-again Christian. God gives each person free will, and it's up to your husband to make that decision for himself. You can influence him through your love, actions, and prayers, but ultimately, it's his choice. The Bible tells us, "So then each one of us will give account of himself to God" (Romans 14:12 WEB).
Secondly, we notice that you've used the phrase "through me" when asking for your husband's salvation. We must clarify that salvation comes only through Jesus Christ, not through any other person. As the Bible says, "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
Regarding the unity in your marriage, it's wonderful that you're praying for this. The Bible tells us, "Let there be no strife, I pray you, between me and you, and between my herdsmen and your herdsmen; for we are brothers" (Genesis 13:8 WEB). However, we must rebuke the idea of controlling your husband's attractions or relationships. This is not biblical and shows a lack of trust in God and your husband. The Bible tells us to put our trust in God, "Trust in Yahweh with all your heart, and don't lean on your own understanding" (Proverbs 3:5 WEB).
Instead of trying to control, pray for God's will in your husband's life and your marriage. Pray for God to remove any temptations and for your husband to have a heart that's devoted to you and God.
Let's pray together:
Heavenly Father, we come before You in Jesus' name, lifting up this marriage. Lord, we pray for unity in their marriage, that they may be one, as You and Jesus are one. We pray for Your will to be done in their lives and marriage. We ask that You remove any temptations and that their hearts may be devoted to You and each other. We also pray for the salvation of the husband, that he may come to know You personally. We trust in You and Your timing. In Jesus' name, we pray. Amen.
