In his commentary on the above verse, J. van Rijckenborgh explains that rebirth is in fact the core problem of the Gnosis. No one can be saved without rebirth. If you actively stand in the process of transformation and transfiguration, you will at some time come to the understanding that there still remains a deep gap between your more or less cultivated state of refinement and the process of rebirth. Or in other words: The Christophorus - the name means: bearer of the Christ - in your being is still not awake enough to carry the Christ-child across the river Lethe, the river of forgetfulness!
