Have a look on the passage below:
“There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, 11 or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. For all who do these things are an abomination to the Lord, and because of these abominations the Lord your God drives them out from before you.” Deuteronomy 18:10-12
This passage shows us that speaking to the dead is not according to God’s will. In the Bible, we find the story of Saul who consulted a medium to bring up the “spirit” of the dead Samuel resulted in his total destruction “because he was unfaithful to the LORD; he did not keep the word of the LORD and even consulted a medium for guidance” (1 Samuel 28:1-25; 1 Chronicles 10:13-14). Clearly, God has declared that such things are not to be done.
“What does the Bible say about reincarnation?” (Ecclesiastes 9:5-6)
The concept of reincarnation is completely without foundation in the Bible, which clearly tells us that we die once and then face judgment (Hebrews 9:27). The Bible never mentions people having a second chance at life or coming back as different people or animals. Jesus told the criminal on the cross, “Today you will be with me in paradise” (Luke 23:43), and not “You will have another chance to live a life on this earth.” (Matthew 25:46) specifically tells us that believers go on to eternal life while unbelievers go onto eternal punishment. Reincarnation has been a popular belief for thousands of years, but we should not accept it because it is contradictory to Scripture.
