We are truly heartbroken to hear about the situation you are facing, and we are here to lift you up in prayer and provide biblical encouragement. Firstly, we commend you for coming to us in Jesus' name, as it is only through His name that we have access to God the Father. In John 14:6, Jesus said I am the way, the truth and the life. No one comes to the Father except through me.
In the midst of your struggles, remember that God is always with you, and He cares for you deeply. It is written Psalm 34:18 "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit" even when it feels like everything is falling apart. Even though you may not feel like your prayers have been answered, but cast your burden on the Lord and believe Galatians 6:9, and do not let yourselves be weary in doing good, for we will reap in due time, if we do not give up.
Regarding your relationship with your husband, we encourage both of you to seek God's will for your marriage especially if he is also a Christian. It concerns us that he has left you. If you are both Christians and committed to the Lord, then God can intervene in your marriage. It is God's desire for marriages to be lifelong commitments between a man and a woman as outlined in Matthew 19:4-6, and you have a husband and a daughter to consider, it is serious. It was said husbands love your wives and wives submit to your husbands as unto the Lord, and finally it was said husbands love your wife as Christ loved the church and gave himself for it. Whatever you must do is forgive and be devoted to your husband and daughter and chase away darkness by loving your husband and child to the fullest.
Below is a prayer for you and your family. Please let our words bring you some comfort as we seek God's will together through this difficult time.
Dear Heavenly Father,
We come before You today, lifting up our sister in Christ who is in desperate need of Your divine assistance, intervention, and comfort. She has reached a point of despair, feeling overwhelmed by the circumstances she faces. Father, we ask that You wrap Your loving arms around her and her child, and reassure her of Your unfailing love and presence in her life.
Lord, we pray for her husband also, and ask Your redirection so that his heart turns back towards You, towards her and towards their marriage. Lord, we pray he is a Christian and therefore knows to do the right thing. Being redeemed, you do not offer reconciliation and forgiveness forever, but we should do this in a Biblical way. We pray for a proper Biblical marriage for them whether He brings the husband back or reminds them to live as brother and sister in the Lord. We pray You show them Your will in their situation, and that this is an opportunity to witness for You. We ask that You provide for their needs, and that You guide her and her husband as they navigate this challenging time.
Lord, especially forgive him of his sins, and soften his heart to be receptive to You and his family in his life. May your obedience to God be an example to both your husband and your daughter to follow. Father also protect your daughter, and give her the ability to forgive, love and obey also. Enable them to train up their daughter to live righteously and serve Him.
Help them also remember Your promise in Psalm 55:22 Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved. Father, strengthen her faith and give her hope in Jesus . Lord, help her husband not feel that he can go back to what he is doing, so he does not feel convinced of the fact that he is wrong in his actions. Make it clearly evident to him through Biblical instruction and the conviction of the Holy Spirit. In Jesus Jesus' mighty name we pray
Amen.
