We have so many beliefs here in this world, so many superstitions, we feel that most of these beliefs are just human imagination. It doesn't matter how many times we imagine all these things, but it will never come true.
The Bible says that no one can decree a thing to come to pass. With respect to how we believe about this superstition or how long we've been coping, such is the case with the subject of incarnation.
The Bible has already made it clear that mankind is expected to die once and after then comes judgment. We cannot die and come back in another form, but imagine that delusion.
How could we believe that in this situation that when we die we'll come back? Who told us so? These are the thoughts that are embodying us as believers. If reincarnation is possible, when someone can come back after being dead.
This makes us to believe that dying and reincarnating will make us anything perfect, which is not true about whether the Reincarnation is true or not and how it concerns the Christian faith.
