March 13

According to the explicit divine Text, teaching the children is indispensable and obligatory. It followeth that teachers are servants of the Lord God, since they have arisen to perform this task, which is the same as worship. You must therefore offer praise with every breath, for you are educating your spiritual children.

The spiritual father is greater than the physical one, for the latter bestoweth but this world’s life, whereas the former endoweth his child with life everlasting. This is why, in the Law of God, teachers are listed among the heirs.

Now you, in reality, have acquired all these spiritual children free and gratis, and that is better than having physical children; for such children are not grateful to their fathers, since they feel that the father serveth them because he must—and therefore no matter what he doeth for them, they pay it no mind. Spiritual children, however, are always appreciative of their father’s loving-kindness. This, verily, is out of the grace of thy Lord, the Beneficent.
