We thank God with you that He in His mercy opened your eyes and delivered you from being drawn deeper into deception and bondage, and we praise Him for saving you from that relationship. What you describe is not love, for love does not manipulate or abuse, and the Lord sees the harm that was done to you and He is your refuge and healer. We agree with you that no one should be drawn into such darkness and we join you in praying that this false religion would be exposed and stopped.
Scripture warns us so clearly about this very danger. We are told, Beware of false prophets, who come to you in sheep's clothing, but inwardly are ravening wolves. Matt 7:15 and Beloved, don’t believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world. 1 John 4:1 There were false prophets also arose among the people, as false teachers will also be among you, who will secretly bring in destructive heresies, denying even the Master who bought them, bringing on themselves swift destruction. 2 Pet 2:1 And no wonder, for even Satan masquerades as an angel of light. 2 Cor 11:14 A charismatic and manipulative spirit that seeks control over others and draws people away from the truth of Christ is not from God, and we rebuke that deception and we pray that the Lord would bring it to nothing. For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world’s rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places. Eph 6:12
We also want to gently point out that your request mentions God but does not mention Jesus Christ, and we want to ensure you know that it is only through Jesus that we have access to the Father and that anyone can be saved, including your ex and those trapped in this group. Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me. John 14:6 and 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. Acts 4:12 If anyone preaches any other good news than the gospel of Christ, let him be cursed. Gal 1:8 This is why we pray for salvation for them, that they would turn from darkness to light and from the power of Satan to God. The Lord desires all people to be saved and come to full knowledge of the truth. 1 Tim 2:4
We encourage you to remain firmly separated from this man and from this group, to continue to test everything against the Word of God, to stay rooted in a Bible believing church where you can receive wise counsel and protection, and to allow the Lord to heal the wounds left by psychological abuse. Remember that you are to be equally yoked with a fellow believer in Christ if you court in the future with marriage as the goal, for God designed marriage between a man and a woman to reflect Christ and the church, and He will guide you to a godly spouse in His timing. Guard your heart and mind in Christ and do not be drawn back into any contact that would open the door to further manipulation.
We pray together now for you and for all those involved.
Father, in the name of Jesus Christ we come before You and we thank You for delivering our sister from deception and abuse. We ask You to heal her heart and mind, to restore what the enemy has tried to steal, and to surround her with Your peace and truth and with godly community. Lord, we lift up this former boyfriend and his loved ones and every person entangled in this false religion. We ask that You would expose every lie, that You would stop the spread of this deception, that You would break the power of manipulation and control, and that You would draw each one to repentance and to saving faith in Jesus Christ alone. Let no weapon that is formed against Your people prosper, and let those who are captives be set free by the truth of Your Son. We pray that You would protect the vulnerable from being led astray and that Your gospel would shine brightly in this darkness. We ask all this in the mighty and saving name of Jesus Christ, our only hope and our Lord, amen.
