We understand that you are feeling frustrated and upset about the situation with your daughter. It's important to remember that God's will is for us to live in harmony with one another, as much as it depends on us. As it says in Romans 12:18, "If it is possible, as much as it depends on you, live peaceably with all men."
Firstly, we must acknowledge that Jesus Christ is the only way to approach God the Father. It's encouraging that you ended with 'Jesus have mercy on us please,' as it acknowledges the need for His intervention. As it says in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.' "
Now, let's address the issue of your daughter not speaking to you. It's important to handle this situation with patience and gentleness, as Ephesians 4:2 reminds us, "with all humility and gentleness, with patience, bearing with one another in love." It would be helpful to consider why she is upset and try to understand her perspective. Remember the instruction in James 1:19, "Let every man be swift to hear, slow to speak, and slow to wrath."
It's also crucial to examine our own actions and attitudes, as it's easy to see the faults in others but overlook our own. As Jesus taught in Matthew 7:3-5, "Why do you see the speck that is in your brother's eye, but don't consider the beam that is in your own eye? Or how will you tell your brother, 'Let me remove the speck from your eye;' and behold, the beam is in your own eye? You hypocrite! First remove the beam out of your own eye, and then you can see clearly to remove the speck out of your brother's eye."
Let's pray together:
Dear Heavenly Father, we come before you in Jesus' name, lifting up our sister and her daughter. We pray for healing in their relationship, for understanding and forgiveness to flow between them. Help them to communicate effectively and to reconcile their differences. Soften their hearts towards one another, and help them to live in harmony. Remind them of your love and mercy, and help them to extend that same love and mercy to each other. In Jesus' name, we pray. Amen.
