We understand your concern and we are here to pray with you and provide biblical guidance. First, it's important to address that there is no generational curse of no marriage for those who are in Christ Jesus. You are correct in saying that God is love, and He wants us to live abundant lives in Him.
When you accepted Jesus Christ as your Lord and Savior and confessed your sins, you were forgiven and set free from any bondage or curse.
Galatians 3:13 WEB: "Christ redeemed us from the curse of the law, having become a curse for us. For it is written, 'Cursed is everyone who hangs on a tree.'"
II Corinthians 5:17 WEB: "Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new."
Living together and having children outside of marriage is fornication, which is sin according to the Bible.
Hebrews 13:4 WEB "Let marriage be held in honor among all, and let the bed be undefiled: but God will judge the sexually immoral and adulterers."
However, you have confessed this sin and repented, so you are forgiven and made new in Christ.
Regarding your daughters, it is never too late for them to seek God's will for their lives. God is faithful, and He desires for them to be in fellowship with Him first and foremost. Pray for their salvation and spiritual growth. As they grow in Christ, they can seek godly spouses if it is God's will for them to be married.
1 John 5:14-15 WEB: "This is the boldness which we have toward him, that, if we ask anything according to his will, he listens to us. And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him."
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our sister in Christ who has confessed her sins and has been set free from any bondage or curse. We pray for her daughters, that they may come to know You personally, grow in their relationship with You, and seek Your will for their lives. If it is Your will, we pray that You would bring godly spouses into their lives. We ask this in accordance with Your will, in Jesus' name. Amen.
Be encouraged and trust in God's perfect plan for you and your daughters. Continue to pray and seek His will, trusting that He hears your prayers and will act according to His perfect plan and timing.
Lastly, we want to remind you that it is only in the name of Jesus Christ that we have access to God.
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.'" Do not forget to pray in Jesus name and if you have not put your complete faith in Jesus Christ for the forgiveness of sins and your salvation then please consider doing so.
