Martinus writes about Christianity with and without reincarnation in Livets Bog 3, 870:
But if one denies reincarnation, even in these days one is taking part in a continuation of the world redeemer’s crucifixion and thereby contributing towards a perversion or falsification of his genuine world-saving wisdom. Without evolution this wisdom would have absolutely no value. Were it not for the fact that one is ‘born again’ and is able to continue through this new life to develop and continue to have experiences leading to more and more knowledge and so be able to put right what one has done wrong, one could not possibly come to ‘reap’ what one has ‘sown’. To ‘see’ God’s kingdom as well as to ‘enter therein’, as Jesus actually told Nicodemus would happen, would be an absolute impossibility without reincarnation. It was clearly obvious to the world redeemer that admittance as a perfect being to ‘God’s kingdom’ was not to be gained through mere ‘clemency’ or ‘absolution’. Otherwise he would have occupied himself solely with ‘absolution’. He would have had no logical reason whatsoever for spending all the time, energy and effort producing precepts, injunctions and ideals for his disciples and for all the other seekers after wisdom, as well as in his sermons to the people. Indeed, what would be the use of all that revelation, if it were only to produce precepts that no terrestrial human being could fulfil, and if ‘mercy’ and ‘absolution’ were actually the crucial factors? No, as we have seen, the world redeemer knew full well that the ideals could not be realized in a single earthly life, but that their fulfilment, on the contrary, would gradually become a reality for each individual over the course of a number of lives as the fruit of his own desires, practice, will and experience. And it is this being's meeting with the highest fruit of his previous lives that Jesus expressly defines as the home-coming of the ‘prodigal son’, that is, his meeting with the Father. At this point the son of God has realized his mistakes and thereby come to the correct recognition and attitude towards his Father and can look upon his own life and eternal identity as a son of God. He has now become the master of matter and consequently of life and death. He now no longer ‘sins’(makes mistakes), but acts perfectly; he is sexually impartial and hence has become all-loving.
