We join you in praising and thanking our Lord Jesus Christ, for He is worthy of all glory and honor. We are grateful that you have come to us with your prayer request, and we stand in agreement with you, seeking God's will and intervention in your life as the Bible instructs us.
You have asked for deliverance from the heaviness and spiritual harassment inflicted by your ex-boyfriend's sister. Firstly, we want to address that the term 'boyfriend' or 'ex-boyfriend' is not necessarily wrong but may imply an unintentional or intentional casual relationship. However, we will not assume that is the case here but will address it in general. We want to remind you that God's design for relationships is clear in His word. In 2 Corinthians 6:14 WEB it says, Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?
We are encouraged that you are standing on the promises of God's word. As it says in John 8:36 WEB So if the Son makes you free, you will be free indeed. We pray for your deliverance from your ex-boyfriend's sister as well.
Let us pray together:
Dear Lord Jesus,
We come before You, lifting up our sister in Christ who is feeling oppressed and harassed. Lord, we ask that You break every chain of heaviness and remove all spiritual harassment from her, as Your word promises in Isaiah 61:7 WEB instead of their shame, that they should have double; and instead of dishonor, that they should rejoice in their portion: therefore in their land they will possess double; everlasting joy will be to them.
We pray that You bring down all strongholds that are causing this harassment, as it says in 2 Corinthians 10:3-5 WEB. For though we walk in the flesh, we do not wage war according to the flesh; for the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds, throwing down imaginations and every high thing that is exalted against the knowledge of God, and bringing every thought into captivity to the obedience of Christ.
Lord, we ask that You heal her from all the pain and suffering that has been caused by this spiritual harassment.
Lord Jesus, we ask this in Your name. Thank you Jesus for your help. May your Kingdom come and may your will be done on earth as it is in heaven.
Amen
We encourage you to continue standing on the promises of God's word and to trust in Him for your deliverance. Remember, our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms, as told in Ephesians 6:12.
Lastly, we want to remind you that it is only in the name of Jesus that we have access to God. As it says 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. Also it is only by the name of Jesus that we can be saved as it says in Acts 4:12. In addition, it is only by the name of Jesus we can ask anything to the Father as it says in John 16:23.
If you have not already, we encourage you to accept Jesus Christ as your Lord and Savior. As the Bible says in Romans 10:9 WEB because, if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes unto righteousness; and with the mouth confession is made unto salvation.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
