We are truly sorry to hear about the trials your family is facing, Anonymous. Let us first assure you that God is a very present help in trouble (Psalm 46:1, WEB).
Firstly, let us pray for your husband's release from jail. We do not know the circumstances, but we trust that God can intervene and bring him out safely. Remember, Jesus came to set the captives free (Luke 4:18, WEB). Let us pray:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We ask for Your mercy and grace upon our sister's husband. Lord, if it is Your will, grant him a swift release from jail. Turn the hearts of those in authority that they may show him favor. In Jesus' name, we pray."
Secondly, let us address your financial struggle. God is our provider, and He promises to supply all our needs according to His riches in glory in Christ Jesus (Philippians 4:19, WEB). Let us pray for your financial breakthrough:
"Lord, we ask for Your divine provision for our sister and her family. You know their needs, and You are able to do exceedingly abundantly above all that we ask or think (Ephesians 3:20, WEB). We rebuke the spirit of poverty and lack, and we declare that they are blessed and not cursed, that they are the head and not the tail, that they are above and not beneath (Deuteronomy 28:13, WEB). In Jesus' name, we pray."
Lastly, let us pray for strength for you and your children. God promises to be the strength of the widow and the father of the fatherless (Psalm 68:5, WEB). Though your husband is not lost, God is still your strength and support in this trying time. Let us pray:
"Dear Lord, we ask for a special anointing of strength and grace upon our sister and her children. Comfort them, Lord, and let them know that You are with them. Grant them peace that passes all understanding (Philippians 4:7, WEB), and help them to endure this trial with faith and patience. In Jesus' name, we pray."
Anonymous, we also encourage you to seek God's will in this situation. Trust that He is working all things together for your good (Romans 8:28, WEB). Use this time to draw closer to Him, and He will direct your paths (Proverbs 3:5-6, WEB).
Lastly, we notice that your request did not mention Jesus Christ. We want to remind you that it is only through His name that we have access to God (John 14:6, WEB). If you have not already, please consider accepting Him as your Lord and Savior. It is only through Him that we can be saved (Acts 4:12, WEB).
