2498 Education for forbearance.... work in the hereafter....
October 6, 1942: Book 33
The human being must train himself to be patient, for this virtue is absolutely necessary if the soul wants to participate in the work of redemption in the beyond. The soul is often resisted more than on earth if it wants to persuade the ignorant and suffering souls to accept admonitions and instructions, and only through utmost patience can it win these souls for itself and then start its work on them. The state of suffering of these souls does not contribute to their willingness to accept, but rather they reject the souls who want to help them, for they still lack all patience as they are imperfect. The already more mature soul, however, must not allow itself to be put off, it must try again and again with tireless patience to get in contact with them, it must lovingly stand by their side and try to change their initial aversion, it must repeat every unsuccessful attempt and thus approach these souls again and again and present to them their painful state and at the same time suggest to them what they should do in order to improve their state of soul. Only extreme patience and great love will bring about success. But this success is unspeakably happy for the helpful being and spurs it on to be constantly active in the spiritual kingdom. The soul that has once tasted this happiness, that has seen into the depths of the kingdom beyond, will never cease to work for the redemption of these beings. Its own state of light enables it to pass on light, and love for the imperfect beings constantly drives it to do so. Yet the gentlest mind is required if the mature soul wants to achieve success. This is why patience has to be practiced on earth, the human being has to be gentle, peaceable and always willing to help his neighbour, then he will also be able to fulfil his task in the beyond, which consists of winning the spiritual beings which are distant from God and making the possessions accessible to them which alone are valuable for eternity....
Amen
