We rejoice with you as you seek to accept Jesus Christ into your heart and turn away from the bonds of demonic influences and paganism. It is crucial to understand that the only way to God is through Jesus Christ, as it is written: "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 WEB
First, we must address the issue of engaging with demonic plants and substances like ayahuasca, shrooms, iboga, and other so-called "medicines." These substances are not from God and opening yourself to them has indeed invited demonic influences into your life. The Bible tells us to be sober-minded and vigilant because our adversary the devil prowls around like a roaring lion, seeking someone to devour. 1 Peter 5:8 WEB
Let us pray for you:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this dear soul who has been entangled in the snares of the enemy. Lord, we ask for Your forgiveness and cleansing upon them, as they have acknowledged and turned away from their involvement with demonic plants and pagan practices.
Father, we pray that the blood of Jesus Christ would cover them completely, breaking every curse, every demonic cord, and every ungodly soul tie formed through these practices. We rebuke any lingering demonic influences and command them to leave, in the mighty name of Jesus.
Lord, we ask that You fill this dear soul with Your Holy Spirit, guiding them towards Your truth and wisdom. Replace any lies and deceptions with Your pure and life-giving Word. Help them to fully renounce their past involvements and to walk in newness of life, in Jesus' name. We also pray that you guide them and convict them concerning ungodly eastern religious practices and mindsets.
Father, we thank You for the power of the blood of Jesus, which cleanses us from all sin and sets the captives free. We declare that this dear soul is freed from witchcraft bondage and guided towards Your truth, in Jesus' mighty name.
In Jesus Christ name we pray, Amen
We encourage you to fully renounce your past involvements with these demonic plants and practices. Confess them as sin to God and turn away from them completely. The Bible tells us, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." 1 John 1:9 WEB
Remember, it is only by the name of Jesus Christ that we can be saved. "in none other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved!" Acts 4:12 WEB
Lastly, we want to address your question about karma. As a believer in Jesus Christ, you are no longer under the influence of karma or any other eastern philosophies. The Bible tells us that "there is therefore now no condemnation to those who are in Christ Jesus, who don't walk according to the flesh, but according to the Spirit." Romans 8:1 WEB
Jesus Christ has set you free, and when you trust in Him, you are a new creation. "Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold, all things have become new." 2 Corinthians 5:17 WEB
Stand firm in your faith and walk in the freedom and truth that Jesus Christ offers. We are here to support and pray for you as you grow in your relationship with Him.
