As Christians we do not believe in a person dying and then coming back to this earth in another lifetime. To each and everyone of us on earth we are all equally given one live and one opportunity, and it is wise that we make the most of it while we have the opportunity to do so with the little time that we have.
Hebrews 9:27 - And as it is appointed unto men once to die, but after this the judgment
There is no two ways about this. According to the passage above we see that what precedes right after death is judgement and not another life. We ought to live our lives with this consciousness. It is good for us to what the truth is so as not be deceived by teachings that are not true.
It is not everything we should take in and believe. Before we agree to any doctrine we must first of verify it and make sure of it corresponds to what God is saying with regards to that matter.
