We are truly sorry to hear about the argument with your daughter-in-law and the current state of your relationship. It's commendable that you've repented and are seeking to reconcile. Remember, the Bible tells us in Matthew 5:23-24, WEB: "If therefore you are offering your gift at the altar, and there remember that your brother has anything against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift."
However, it's important to understand that true repentance is not just feeling sorry, but also involves a change in behavior and attitude. You mentioned feeling convicted, but it might be helpful to explore why. Proverbs 28:13 says, WEB: "He who conceals his sins doesn't prosper, but whoever confesses and renounces them finds mercy." Ensure that you've acknowledged any wrongdoing not just to yourself, but to God and your daughter-in-law as well. This may be a good start.
It's also crucial to give your daughter-in-law space if she needs it. Pursue peace and reconciliation, but understand that she might need time to heal and forgive. We need to follow Jesus's teachings of love and kindness, even when others may not initially receive them. Jesus tells us in Matthew 5:44 to "Love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you." This might feel challenging, but it's what we are called to do. It's important to note. You do not mention praying in Jesus name or acknowledging him in your request. It is only by his name and his blood shed on the cross that we can be saved. Jesus then gives us access to pray to our heavenly father. Proverbs 3:5-6 says "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
Let's pray together:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up this beloved parent. Lord, we know that you hate division and desire unity among your children. We ask for your healing and reconciliation in this relationship. We come to you in obedience to you as your word says in 1 John 1:9, WEB: "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." We pray this relationship can be restored through your son Jesus.
Please soften your daughter-in-law's heart, Lord, and give her the courage to forgive and reconcile. Please give the parent the strength and patience to wait, the wisdom to know how to approach this situation, and the grace to continue showing love and kindness.
We pray for every unspoken need, heal every wound, and break every chain of resentment or unforgivness. Guide them through your holy spirit into what your will is for their life. Please bless them and save them if they are not already believers in the holy name of your son Jesus.
In Jesus Christ's name we pray, Amen.
In the meantime, continue to pray for your daughter-in-law and trust God with the outcome. Trust that Rom 8:28 is true, "We know that all things work together for good for those who love God, to those who are called according to his purpose", and God will do His will in her life. Also, remember the Parable of the Prodigal Son. The Father waited patiently for his child to return the door is always open for us to come home. Continue to pray and ask your heavenly father in the name of Jesus Christ. Praise Jesus for his blood on the cross that allows us access to pray to our heavenly father.
