We are truly sorry to hear about the struggles you are facing in your marriage. We will stand with you in prayer and offer some biblical guidance.
Firstly, we want to remind you of the power of love and kindness, even in the face of anger. "Don’t let any evil talk come out of your mouths, but only what is useful for building up, so that it gives grace to those who hear. Let all bitterness, wrath, anger, outcry, and slander, be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, just as God also in Christ forgave you" Ephesians 4:29,31-32 WEB.
It's crucial to understand that your husband's behavior may be influenced by his condition, but it does not excuse his actions. He needs help beyond your own ability to support and provide. Pray for him, that God would intervene and guide him to seek the professional help he needs. "Bear one another’s burdens, and so fulfill the law of Christ" Galatians 6:2 WEB.
At the same time, it's important to set boundaries to protect yourself and your children from harmful behavior especially verbal abuse. "If anyone doesn’t provide for their own, and especially their own household, they have denied the faith, and is worse than an unbeliever" 1 Timothy 5:8 WEB. This does not mean leaving or disrespecting your spouse, but rather making it clear that certain behaviors will not be tolerated.
Let's pray together:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up this sister and her husband. Lord, you know the struggles they are facing, and we ask for your divine intervention. Please guide her husband to seek the help he needs, and give her the strength and wisdom to set healthy boundaries. Protect their youngest son from the pain of hurtful words, and heal his heart. We are so grateful for the power to approach your throne of grace through the sacrifice of Jesus Christ who shed his own blood for our sins.
In Jesus Christ's precious name, we pray and plead for your intervention, Amen.
Lastly, we urge you to examine your own heart and actions, ensuring that you are not provoking or escalating the arguments. Seek God's guidance in how you can be a blessing to your husband and encourage him with the word of God. "A gentle answer turns away wrath, but a harsh word stirs up anger" Proverbs 15:1 WEB.
As a final word, anger is a human thing that we all deal with and experience. But it is not our job to try and change one another but instead to change ourselves to become more and more like Jesus. The only way to do that is to spend more time with him by praying, reading the Bible, and being in a fellowship of believers.
