The book of life explains that there's judgement for humans when they die , (Hebrews 9:27). Being reborn is fake because it's was not written in the scripture.The imagination of being of reincarnated as another creature does not make sense since the goal is to be perfect. 2 Timothy 3:13 says that wickedness and deceit will continue, showing that fake topics like being reborn deceive people. Jesus Christ is the owner of church and he's the first born raised from the dead.(Colossians 1:18).
The hope of believers of Christ has only one hope which is salvation through God (Ephesians 4:4)
Being reborn weaken that hope.our work as a Christian is to do things that will please him and trusting his plans to be true.salvation is from God's miracle and the scripture directs every move we make.
