In reply to thy letter, I am obliged to be brief: Praise thou God that thou hast succeeded in becoming a teacher of young Bahá'ís, young trees of the Abha Paradise, and at the same time art able to benefit the other children as well. 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.
