As believers we do not believe in someone dying and then coming back to back to this earth in another form. We are all given one live and one opportunity in this life we find ourselves, and it is wise that we make the most of it while we have the opportunity to do so.
Hebrews 9:27 - And as it is appointed unto men once to die, but after this the judgment
There are no two ways about it. What precedes after death is judgement and not another life. We ought to live our lives with this consciousness. It is good for us to know the truth and not be deceived by teachings that are not true.
Not everything we should take in and accept. Before we agree to any doctrine we must first of all fine out and make sure of it corresponds to what God is saying concerning that matter.
