We understand your heart's cry for your family, and we stand with you in prayer. Let us first remember the words of Jesus in Matthew 19:26 WEB, "With God all things are possible." God can turn around any situation and soften any heart.
However, we noticed that you did not mention the name of Jesus Christ in your request. We want to remind you that it is only through Jesus that we have access to God. As it is written in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" Therefore, we will pray to God the Father in the name of Jesus Christ.
Let us pray together:
"Dear Heavenly Father, we come before you in the precious name of Jesus Christ. We lift up the family of the one who has submitted this request to you. Lord, you know the details of every situation they are facing. We ask that you would work in the hearts of each family member. Draw them to yourself, Lord, and let them experience the transforming power of your love.
We pray for the salvation of each one, that they would come to know Jesus Christ as their personal Lord and Savior. We ask that you would heal any broken relationships, and bring peace and unity to their home.
Help them to walk in your ways, according to your word. As it is written in Ephesians 5:21-6:4 WEB, help them to submit to one another out of reverence for Christ, and let the children obey their parents in the Lord, for this is right.
We ask all these things in the mighty name of Jesus Christ, our Lord. Amen."
We encourage you to continue praying for your family and trusting God for their salvation and unity. Remember, the effective, earnest prayer of a righteous person accomplishes much (James 5:16 WEB). Keep standing in the gap for them, and do not grow weary in doing good, for in due season you will reap, if you do not give up (Galatians 6:9 WEB).
