Let's begin by addressing the concerns surrounding your sister's baptism and the subsequent spiritual struggles she's been experiencing. It's crucial to understand that baptism is a symbol of our faith and commitment to Jesus Christ, and it should be accompanied by a genuine conversion and repentance from sin.
Firstly, it's important to note that the presence of demonic influences could be due to several factors. If your sister was involved in witchcraft before her baptism, it's possible that she did not fully renounce her past practices and commitments. The Bible tells us, "Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers will inherit the kingdom of God" 1 Corinthians 6:9-10 WEB. Witchcraft and other occult practices are included in these sins that separate us from God.
Your sister's inability to read the Bible, avoidance of worship, depression, and health issues could be signs of an unaddressed spiritual stronghold. We must remember, "For though we walk in the flesh, we do not wage warfare 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" 2 Corinthians 10:3-5 WEB.
Regarding rebaptism, the Bible does not prescribe multiple baptisms. Baptism is a one-time act of obedience and identification with Christ's death, burial, and resurrection. However, if your sister's initial baptism was not accompanied by genuine repentance and faith, it might not have been a true baptism in the biblical sense. It's more important for her to genuinely repent, turn to Jesus Christ, and walk in His ways. The power of Jesus in her life will be the greatest testament of her faith.
Let's pray for your sister:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up our ### who is struggling spiritually. We pray that You would reveal to her any areas of her life that are not fully surrendered to You, and grant her the grace to repent and turn to You completely with all her heart, soul, and mind. We rebuke any demonic influences in her life and claim her meaning in Jesus Christ. We claim her mind, soul, heart, and body for Jesus Christ and plead the blood of Jesus Christ over her. We ask for Your healing touch on her body, mind, and spirit according to your will for her. We also ask You to restore with the Holy Spirit and fill her to overflowing with Your presence. In Jesus' name, we pray. Amen.
We encourage your sister to seek counsel from a pastor, experienced spiritual leaders, or a godly counselor who can guide her through this process. It's also important for her to surround herself with a supportive community of believers who can pray with her and hold her accountable. We did not notice the name Jesus Christ, Christ, or Jesus in your request. This is important because it is only by the name of Jesus Christ that we can be saved and approach God Almighty. It is also under the authority of Jesus Christ that we can cast out demons and repel attacks of the devil. Please keep these things in mind for future prayer requests.
