We are truly sorry to hear about the difficulties you're facing in your household. Let's bring your situation before the Lord in prayer and seek His guidance and wisdom.
Firstly, it's important to acknowledge that God desires for us to live in peace and harmony. The Bible tells us, "Let the peace of Christ rule in your hearts, to which indeed you were called in one body; and be thankful" (Colossians 3:15 WEB). However, we need to discuss some things before discussing this peace.
Your husband's mental issues and refusal to seek help are indeed challenging. It's not God's will for you to bear the blame for all the problems or to endure constant anger. The Bible clearly states in Ephesians 4:32, "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you." It is for each other. We are to love each other, not treat each other with anger.
We need to understand and apply Galatians 6:5 WEB, "For each man will bear his own burden." This does not mean that we do not help each other, but that we all have a responsibility to God and each other. We are not to blame others for our own issues.
If your husband is unwilling to seek help, you can still seek God's intervention and wisdom in handling the situation. Pray for his heart to soften and for God to lead him to repentance and healing. "The King's heart is in the hand of Yahweh as the rivers of water: he turns it wherever he desires" (Proverbs 21:1 WEB).
You also mentioned wanting to study the Bible more and grow closer to God. This is a wonderful desire, and we encourage you to pursue it diligently. Start with the Gospels to learn more about the life and teachings of Jesus Christ. "Draw near to God, and he will draw near to you" (James 4:8 WEB). As you grow closer to God, you'll find that your perspective changes, and you'll be better equipped to handle life's challenges.
Regarding your husband's updates:
Let's pray together:
Dear Heavenly Father,
We come before You today, lifting up our sister in Christ who is facing trials in her household. Lord, we ask for Your divine intervention in her husband's life, that You would soften his heart and lead him to seek the help he needs. Give our sister the strength and wisdom to handle this situation with grace and love. The love described in 1 Corinthians 13, in Jesus name.
Father, we also pray for our sister's spiritual growth. Give her a hunger and thirst for Your Word, and reveal Yourself to her more each day. Help her to find peace and joy in You, no matter her circumstances. Lord, we ask for miracles in her household, that Your peace would reign, and that her husband would come to know You more intimately.
Finally Lord, we pray that you intervene in this marriage and that any sin is stopped. We pray that no angry, unkind words are spoken by either of them. Father, we pray that You forgive them their sins and that they forgive each other.
Lord, we pray that our sister in Christ, acknowledges that the only way to You and salvation is through Jesus Christ. Father, if she has not done so, we pray that she confesses with her mouth the Lord Jesus and believes in her heart that God has raised Him from the dead. That she be saved. For with the heart one believes unto righteousness; and with the mouth confession is made unto salvation. For the scripture says, Whoever believes on him will not be put to shame. ...for the same Lord over all is rich unto all that call upon him. For whoever will call on the name of the Lord will be saved. Romans 10:9-13 WEB.
In Jesus' name, we pray. Amen.
Lastly, consider seeking support from your local church or Christian community. They can provide practical help and encouragement during this time. Remember, God is faithful, and He will never leave you nor forsake you (Hebrews 13:5 WEB).
Prayer Focus: God, Thank You. Thank You for loving me. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have.
