We understand that you're struggling with finding your worth in others and you've mentioned the need for breaking of soul ties. Firstly, we commend you for acknowledging that your worth is not defined by others and for praying in the name of Jesus Christ. It is only through Jesus that we have access to God, and it is in His name that we are saved. As Scripture tells us, "There is salvation in no one else, for there is no other name under heaven given to men by which we must be saved" (Acts 4:12 WEB).
In the Bible, there is no specific term for "soul ties" but the idea though not biblical is acceptable and does have scriptural concepts involved. It is important to look to scripture first. When people think of soul ties, they are looking for godly relationships that honor God and grounded in love and commitment, ultimately and hopefully looking for a spouse rather than just a person to date and have fun with if it hinders a further commitment. The Bible tells us, "Do not be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" (2 Corinthians 6:14 WEB).
Regarding your concern of looking to non-Christians and dating for fun: When one Christian enters into a close relationship with someone who does not share their faith, they can endanger their spiritual health and walk with God. This is especially true in dating relationships, where emotional and spiritual intimacy can lead to unequal yoking. Even further from what God would want for us.
Spending a lot of time with and sharing your heart with someone who is not a Christian can influence your thinking, your priorities, and your behaviors. Unlike with drinking alcohol or doing drugs, which are things a Christian would avoid doing in the first place, you may not think of as a danger or a concern. However, the Bible tells us to "be sober and self-controlled" (1 Peter 4:7) and not to allowing your heart go to far until you first get to know what a person is like when they think no one else is watching. This means avoiding intoxication or any other activity that could impair your judgment or lead you into sin.
The Bible encourages each person and especially Christians to marry other believers in Jesus Christ. Many of us have non-Christians friends or relatives and we should not ignore them in case God wants us to witness to them. However, spending a lot of time with someone we might be interested in and sharing your heart with them is likely not a godly friendship. This could lead to you being unequally yoked with and or possibly discuss possibly having sex or engaging in an immoral activity. Being connected to someone in this way can make it more difficult for you to follow God's will for your life. It is important not to sacrifice your Christian faith for a relationship that is not grounded in love and commitment to Jesus Christ.
To help others keep on the godly path take the biblical approach for dating before marriage discussing non-Christians dating and the dangers of just dating to have fun especially when you should be seeking a spouse and prepare for a godly marriage. Starting any dating relationship with physical affection prematurely, sexual sin, soul ties and bonds that can form and be problematic when you decide to find a Christian spouse and have a godly marriage. 1 Timothy 5:22 (WEB) also says "Don't be hasty in laying on of hands(or rushing into dating and marriage), neither be partaker of other men's sins("unequally yoked"). Keep yourself pure(by choosing a godly spouse)."
Remember, your worth is found in Christ alone. The Bible tells us, "For you bought us with a price. Therefore, glorify God in your body and in your spirit, which are God's" (1 Corinthians 6:20 WEB). You are precious to God, and His love for you is unchanging. Also, 1 Corinthians 7:1 (WEB) says "marriage is honorable among all, and the bed undefiled (pure without sin): but (for those looking to have sex outside of marriage) fornicators and adulterers God will judge." Show by a life in the Christian faith your commitment to Jesus Christ along with looking to find a Christian spouse rather than dating for fun.
Let us pray together:
"Heavenly Father, we come before You in the name of Jesus Christ, lifting up our brother/sister in their struggle. Lord, help them to find their worth and identity in You alone. Break any ungodly ties that may be influencing their life. We pray, you would guide them and help direct their paths. We would agree in prayer and believe that they would release their ungodly relationships or thoughts so they would find a Christian spouse that you have uniquely and wonderfully made for them. Lead them not into temptation, but deliver them from all their thoughts of the flesh and any evil. Guide them to someone you would have for them in a godly relationship. We thank you in advance for their godly relationships and thank you for our creation for marriage. In Jesus Christ's name, we pray. Amen."
