We are deeply sorry to hear about the struggles you're facing in your marriage, Serah. Let us come together in prayer and seek God's will for your situation.
Firstly, we commend you for your desire to fight for your marriage. It is clear that you hold the sanctity of your union dearly, as God intended (Matthew 19:6, WEB: "So that they are no more two, but one flesh. What therefore God has joined together, let no man separate.").
However, we must address some issues with biblical principles. Addiction is a form of bondage that God wants to set your husband free from (Galatians 5:1, WEB: "Stand firm therefore in the liberty by which Christ has made us free, and don't be entangled again with a yoke of bondage."). We will pray for his deliverance and healing.
Resentment is a natural human response, but God calls us to forgive as He has forgiven us (Ephesians 4:32, WEB: "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you."). We encourage you to approach this situation with a forgiving heart, knowing that God will judge righteously.
We also note that you've asked for Yahweh's intervention. We want to remind you that it is through the name of Jesus Christ that we have access to God (John 14:6, WEB: "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"). It is by His name that we are saved and can approach the throne of grace with confidence (Hebrews 4:16).
Let us pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up our sister Serah and her marriage. Lord, we ask for Your divine intervention in their union. Heal her husband from his addiction, Lord, and set him free from the bondage of sin. Soften both of their hearts, Lord, and help them to forgive each other as You have forgiven us. Guide their meeting today with the family, Lord, and let Your will be done. In Jesus' name, we pray. Amen."
Stay strong in the Lord, Serah. Trust that God is working in your situation, even when it's hard to see. Continue to seek Him and His will for your marriage.
