Many religions supported idol worship in the New Testament world. Idolatry was a major concern for NT writers, particularly Paul.
For while one saith, I am of Paul; and another, I am of Apollos; are ye not carnal? Who then is Paul, and who is Apollos, but ministers by whom ye believed, even as the Lord gave to every man? I have planted, Apollos watered; but God gave the increase. 1 Corinthians 3:4-6

Lord Jesus, I believe you are the son of God, and you died for my sins and rose again from the dead, I trust you for cleansing and forgiveness, and you have received me as a Child of God. If there is any resentment or unforgiveness for anyone, I lay it at your feet and ask you to forgive me. I ask your forgiveness for being involved in other religions, witchcraft, or the occult seeking other gods. I acknowledge this as sin and loose myself right now in Jesus name. And now, Lord Jesus, I come to and yield my body, mind, and spirit to you. I give you my all. I surrender my tongue to you to be an instrument of righteousness to worship you in a new language. By faith, I receive it now, Lord in Jesus name. Amen.
