We understand your concern and will pray for your situation together. Firstly, it's important to remember that God calls us to honor our family, but also to live in peace with all men, our behavior as Christians should be exemplary, We are reminded of this in Romans 12:18 WEB If it is possible, as much as it is up to you, be at peace with all men.
However, it's crucial to address the behavior of your aunties and uncle. If they claim Christ but do not live according to His teachings, then they need to address this in their own lives. You can't necessarily change their hearts yourself, but we can pray for them together.
Instead of focusing on their misbehavior, ask for them to have a change of heart and to seek God's will and peace in their lives. This is very important to keep our prayers in line with God's will and not just a desire to avoid discomfort. We can pray for God's will in their lives, for Him to bring correction and for Him to also give you and the rest of the family the patience and love to deal with any issues that do arise.
We also pray for you and your family to keep your hearts aligned with God's will and to continue to show love and respect to your family, even if you are not shown it in return.
Rebuking relationships that do not align with biblical principles, we should also pray for them to renew their hearts and minds with the Word of God. Remember that it is the kindness of God that leads us to repentance. We are also reminded to remove the log out of our own eyes before removing the spec out of our neighbors.
We pray to remind them not to seek attention for themselves but to give honor and glory to God in all things. 1 Peter 5:5-6 WEB Likewise, you younger ones be subject to the elder. Yes, all of you gird yourselves with humility, to subject yourselves to one another, for God resists the proud, but gives grace to the humble. Humble yourselves therefore under the mighty hand of God, that he may exalt you in due time.
It is very important to remember if one is a Christian or not, God will not be mocked. Being rich does not make us better than other people, but being poor in spirit and knowing our need for God is precious in His sight.
We pray for their hearts, that they may know and walk with Jesus Christ. We pray for their eyes to be opened to their behavior and for their hearts to be softened to hear God's correction. We pray for peace in your home and for all arguments, strife and dissension to cease. We pray for unity and love to reign in your family. We pray for God to work in your aunties and uncles' hearts to bring correction and peace to them and to your whole family.
Please also remember to pray for yourself and your family to also have the heart of Christ towards them. Do not be bitter and unforgiving, but rather remember to pray for them.
