We stand with you, dear brother, in the unity of our faith, echoing the sentiments expressed earlier and adding our voices to your plea. Your situation is indeed challenging, but we find solace and hope in the unchanging Word of God.
Firstly, let us remind ourselves of God's heart for marriages, "For I hate divorce, says the Lord, the God of Israel" (Malachi 2:16 WEB). God's design for marriage is a covenant, a lifelong commitment, and He desires for it to be a reflection of His own unfailing love for us. Let us, therefore, plead with God to strengthen your marriage, to soften hearts, and to bring reconciliation and healing.
We must also address the root issues, as our sister in Christ has wisely pointed out. Constant quarreling can be detrimental to a home. Let us remember the wisdom of Proverbs, "Better is a dry morsel with quietness, than a house full of feasting with strife" (Proverbs 17:1 WEB). Let us strive for peace and understanding in our homes, seeking to resolve conflicts biblically and in love.
In managing your finances, let us trust in God's wisdom. "But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well" (Matthew 6:33 WEB). God calls us to be good stewards of our resources, trusting Him with all our needs.
Your children, too, are precious in God's sight. Let us continue to love them unconditionally, as God loves us. Let us pray for their hearts to be softened, and for them to return to you. Remember the story of the prodigal son (Luke 15:11-32 WEB), who, despite his wandering, was welcomed back with open arms. Our God is a God of second chances, and we serve a God who can change hearts.
Let us join together in prayer:
"Dear Heavenly Father, we come before You in the name of Jesus, lifting up our brother and his family. Lord, we ask for Your intervention in their marriage. Soften their hearts, bring understanding and reconciliation. Help him to trust in You completely, and not rely on his own understanding. Guide him in his finances, and bless his children. Remove the spirit of depression and anxiety, and fill him with Your peace and joy. In Jesus' name, we pray. Amen."
Brother, we encourage you to keep praying, trusting in God, and seeking His will. Remember, "with God all things are possible" (Matthew 19:26 WEB). It's never too late for God to intervene and restore what is broken. Let us hold fast to our faith, for "the effective, fervent prayer of a righteous man avails much" (James 5:16 WEB).
