The lectures and questions-and-answers in this themed issue illuminate the spiritual meaning of the cross. The cross points human beings to the higher goals of life; it reminds them of the willingness to make sacrifices, the peacefulness and the humility of Christ, who died for the salvation of humankind. For the believing Christian, the cross is a walking-staff throughout life. They were baptized in the sign of the cross, and it holds significance for them until the final hour – indeed, beyond this final hour. When they have long since ceased to have any relationship to this world, the cross still stands over their grave. It is always the cross – it is the symbol of faith and hope. The cross has become a memorial not only on earth: in the world beyond it is also of great significance. In one lecture of this themed issue, it is reported how the deceased who in their earthly life never looked up to the cross and who did not fulfill their life tasks are able to achieve a change of attitude with the help of the cross.
