We understand that you're going through a difficult time, facing abuse and a legal battle. Firstly, we want to assure you that you're not alone in this fight. God is with you, and He is your strength and shield.
Let's look at the verse you mentioned, Isaiah 54:17 in the WEB translation: "No weapon that is formed against you will prevail; and you will condemn every tongue that rises against you in judgment. This is the heritage of Yahweh’s servants, and their righteousness is of me," says Yahweh." This verse reassures us that God is our protector and that He will not let any weapon formed against us prosper. He will bring us victory and justice.
However, we want to address that the use of 'amen' is not enough to submit the request to God. As it is said in 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", it is only through the name of Jesus Christ that we have access to God. There is no other name by which we can be saved. Acts 4:12 WEB "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!”
Let us pray together:
Dear Lord Jesus Christ, we come before You, lifting up our brother/sister who is facing abuse and a legal battle. We declare that no weapon formed against them will prosper. We ask You to intervene in this situation, protect and guide throughout this legal battle to bring victory and put an end to the abuse. We pray that You will strengthen them and give them the patience and courage to endure. Jesus, we also pray that you give wisdom and guide the authorities so that the truth will be revealed and that justice will be done. We pray knowing that all things are possible through You.
When you are talking to God, we should always end in the name of Jesus Christ. If you have not been born again and received Jesus Christ as your savior, you should pray to God to forgive your sins and accept Jesus Christ as your Lord and savior. If you have any questions, concerns, or need further clarification, please feel free to ask. We are here to help guide you through God's Word.
