Thank you for sharing your heart so honestly. Your desire for protection for you and your children, for peace and strength and guidance, and for God to provide stability through your work is a right and good prayer, and your desire to leave justice in God's hands rather than seeking revenge honors Him.
God's Word teaches that salvation and standing before Him rests entirely on His grace through the finished work of Jesus Christ. It is not our effort or goodness that saves us, but believing in the One He sent, trusting what Jesus has already accomplished. Because that work is complete, you can come boldly to His throne of grace to find mercy and help in your time of need, not as one coming to earn pay for work done, but as a child coming to a Father who has already provided for you. If you have not already done so, place your full trust in Jesus alone for your salvation, and rest in what He has done for you.
Scripture also shows that God is at work in you before He works through you. Often His work involves shaping and refining, and that shaping can be painful when difficult edges are being removed. You may not understand why certain hard things are allowed, but He uses these testings to form character and maturity in you. That is why we are told to count it joy when we face trials, not because the pain itself is joyful, but because God is using it to prepare you for the good plan He has for your life. He who began a good work in you will be faithful to continue it until Christ returns. The work He is doing now is part of making you complete.
You asked for prayer for your work and for a better shift that allows you to care for your children. God is the one who gives wisdom and stirs hearts to do the work He calls us to, and He delights to accomplish His purposes through willing hearts. It is right to ask Him to open the right doors, to provide work that meets your family's needs, and to give you stability and strength to keep pressing forward. He sees your diligence to provide for your children and He is able to make a way where you cannot see one. Waiting on Him can be hard, and our impatience can get in the way, but He is faithful to work things out in His time and for your good.
You also shared about the hurt caused by your children's father and your prayer for justice and accountability without revenge. God is a God of righteousness and justice, and He desires that justice prevail. In this world, even where justice should be found, it often falls short and people do not receive what is fair. Truth can seem fallen in the street and fairness hard to find. The Lord sees this. He is not indifferent to wrongdoing, and He will deal with all things justly in His way and time. Your choice to leave what you cannot handle in His hands is the right one. Scripture calls us not to avenge ourselves but to trust Him to repay rightly, and to pray that those who have done wrong would come to see the hurt they have caused and be brought to accountability.
I am praying for you and your children, that God would surround you with His protection, fill your home with His peace that passes understanding, give you strength for each day, and guide your steps. I am asking Him to provide for your work needs, to open a door for a shift that brings stability, and to help you see better days ahead. I am also praying that He would bring conviction where it is needed, that justice would be done according to His perfect righteousness, and that you would be able to rest in His care knowing He is working in you and for you.
May you continue to trust in the grace by which you are saved, submit to His shaping hand even when it is difficult, and rest in the finished work of Jesus as you look to Him for all you need.
