We understand that you're facing a number of challenges, Anonymous.
Firstly, we are directed to pray: for all people ask God for all to be saved and to come to the knowledge of the truth and for kings and for all who are in authority that we may lead a tranquil and quiet life in all godliness and reverence, and that all men should pray in all places, lifting up holy hands, without wrath and doubting. So, we are happy to pray for both you and your husband, and your family.
It's important to remember Jesus is the only way to God. We have sinned and the wages of sin is death but the gift of God is eternal life through Jesus Christ our Lord. If when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. For there is one God, and one mediator between God and men, the man Christ Jesus. Believe in the Lord Jesus Christ, and you will be saved. IJN (WEB).
Regarding your husband, we pray that God guides his steps and grants him wisdom, trusting that if any of you lacks wisdom you should ask God, who gives generously to all without finding fault, and it will be given to you. Yet if any man seem to be religious, not bridling his tongue, but deceiving his heart, this man's religion is vain. Pure religion and undefiled before our God and Father is this: to visit the fatherless and widows in their affliction, and to keep oneself unstained by the world. But whoever has the world's goods, and sees his brother have need, and closes his heart of compassion against him, how does the love of God remain in him? My little children, let's not love in word only, neither with the tongue only, but in deed and truth (WEB). A well lived life is a life lived in recognition of the precious gift of salvation. It does not take when it can receive. If you are the head of the home you should make godly choices in the service of God. We pray for this.
Concerning unity in your marriage, we pray that both of you would be filled with the knowledge of his will, gaining wisdom and understanding so that you can live lives that are worthy of the Lord and pleasing to him in every way. (Psalm 119:66 WEB). Realize that the two of you should be connected to each other as both of you are supposed to be connected to Jesus as you are part of his body. Therefore, what God has joined together, let no man separate. Separation is not godly nor can it be solved by a lawyer unless a lawyer is involved because of sin. You should forgive, As Y'hshua said, 'Father, forgive them, for they do not know what they do.'
Marriage means loving self-sacrifice. Sacrifice for Christ that your children would be willing to stand for him because of your example. This cycle should continue in the cycle of marriage and faith. Being of both of you should focus on being fit for service to master and being of husband and wife, though it is often recommended that a pastor should be the husband of one wife this is also true of a husband. We pray for this.
For your concerns about financial provision and a stable home. It is true that it is good to live in peace and safety. However, you should trust in God. God said: Seek first God's Kingdom, and his righteousness; and all these things will be given to you as well so do not worry. IJN
Regarding your in-laws and the legal matters, we encourage you to act with love and forgiveness but be sober minded. "If it is possible, as much as it is up to you, live peaceably with all men." Be careful of division because every kingdom divided against itself is brought to desolation, and every city or house divided against itself will not stand. We pray for this.
Beloved, let us love one another, for love is of God; and everyone who loves is born of God, and knows God. By this we know love, because he laid down his life for us and we ought to lay down our lives for the brothers. But if a man has the world's goods, and sees his brother have need, and closes his heart of compassion against him, how does the love of God remain in him? My little children, let's not love in word only, neither with the tongue only, but in deed and truth (WEB). IJN
Lastly, remember that God is faithful, Who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it.
