We hear the deep ache in your heart for your daughter and we join with you in bringing her before the throne of grace in Jesus' name. To see a child turn away from God and consider abandoning the covenant of marriage and the precious family God has entrusted to her is a heavy burden, and we weep with you over this.
We must speak the truth in love about what God says concerning marriage. Marriage is not a contract to be broken when feelings change or when sin enters in, it is a holy covenant before God between one man and one woman for life. Jesus said, What therefore God has joined together, don't let man tear apart in Matthew 19:6 and also For I hate divorce, says Yahweh, the God of Israel in Malachi 2:16. The desire to leave a marriage of many years with beautiful boys is not from the Lord, and we must lovingly rebuke that plan. Those boys are a heritage from Yahweh as Psalm 127:3 tells us, and they need the stability and love of both their mother and father under one roof. For your daughter to walk away would bring deep wounds to her husband, her children, and to herself, and would not honor God.
We also must address the sin itself. Your request says she has sinned. Scripture says for all have sinned, and fall short of the glory of God in Romans 3:23, but sin has consequences and must be repented of, not used as a reason to compound sin with more sin by breaking the marriage vow. If this sin involves adultery or sexual immorality, God calls that fornication and adultery and says You shall not commit adultery in Exodus 20:14, and that marriage should be held in honor among all, and let the bed be undefiled in Hebrews 13:4. Yet there is hope, for If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness in 1 John 1:9. God is able to forgive, restore, and heal what is broken if she will turn back to Him with a repentant heart.
We notice your request did not mention the name of Jesus Christ, and we want to gently remind you that it is only through Jesus that we have access to the Father and that any of us can be saved or restored. Jesus said I am the way, the truth, and the life. No one comes to the Father, except through me in John 14:6 and There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved in Acts 4:12. Your daughter's greatest need is not just to save her marriage, but to be reconciled to God through faith in Jesus Christ, believing that He died for her sins and rose again. If she will confess with her mouth that Jesus is Lord, and believe in her heart that God raised him from the dead, she will be saved as Romans 10:9 promises. We pray she will remember the prodigal path and return home to her Father as in Luke 15:18-20.
So we encourage you to continue to love her without condoning her sin, to speak the truth with grace, to stand firmly for the sanctity of her marriage, and to pray without ceasing. Do not encourage or make it easy for her to leave, but rather urge her toward repentance, counseling with a faithful pastor, and reconciliation with her husband where possible. God can redeem even the darkest season. With God all things are possible in Matthew 19:26.
We pray together for you, for her, for her husband and for those precious boys.
Father in heaven, we come before You in the mighty name of Jesus Christ, our only Savior and mediator. We lift up this dear daughter who has turned away from You. Lord, convict her heart by Your Holy Spirit, bring her to godly sorrow and true repentance for her sin, and draw her back to Yourself. Soften her heart toward You and toward her marriage covenant. Help her to see the beauty and holiness of marriage and the sacred trust of her children. We pray You would place a hedge of protection around her marriage and not allow the enemy to destroy it. Give her husband strength and grace to love as Christ loved the church and to extend forgiveness as You have forgiven us in Ephesians 4:32. Protect those beautiful boys from confusion and hurt, and let them see the power of Your restoration. Give this praying parent wisdom, courage, and peace that passes understanding, and help them to not grow weary in praying and loving. Restore what the locusts have eaten, Lord, and let this family be a testimony of Your redeeming love. We ask all this in the name of Jesus Christ, Amen.
