My question is that on several occasions diviners have said that I come from the sea. It appears that a spirit follows me and sometimes the diviners see it. One of them once told me that he does not think I will go to heaven because of that. Is that true now that I have received Christ as my Lord and savior?
The Bible tells us to have nothing to do with diviners, and this includes psychics, fortune tellers, astrologers, palm readers, and others of their kind. He called these things detestable to Him, and said the practice of such things by the nations who were occupying the Promised Land at the time was the reason He was sending the Israelites to drive them out (Deut. 18:10-11).
Because of the cross, indulging in such practices is no longer punishable by death. But you can see that God has a serious dislike for them. He sees them as the practice of a false religion because He alone knows the future (Isaiah 44:6-8).
If you believe that Jesus died for your sins and rose again, God has forgiven you for all your sins, including the one of consulting anyone other than Him for answers about your future. And His promise from John 3:16 that all who believe in His Son will have eternal life cancels out anything and everything anyone else has told you. You need no longer be concerned, “For no matter how many promises God has made, they are “Yes” in Christ” (2 Cor. 1:20).
