He is God.

O ye children of the Kingdom! Give thanks unto God that, at this tender age, ye have entered into the Divine Kingdom. The bounty and bestowal of God have surrounded you. While ye were yet children, He chose you and elected you. Ye became the intimates of His mysteries, whilst those of riper age remained deprived. This is naught but a divine bestowal. Therefore give ye thanks unto God, saying:

O Compassionate God! O Lord of Hosts! Praise be unto Thee that Thou hast preferred these little children over the full-grown and mature, and bestowed upon them Thy special favours. Thou hast guided them. Thou hast been kind to them. Thou hast conferred upon them illumination and spirituality. Grant us Thy confirmation so that, when we grow up, we may engage in service to Thy Kingdom, become the cause of educating others, burn like radiant candles and shine like brilliant stars. Thou art the Giver, the Bestower, the Compassionate.

—‘Abdu’l‑Bahá
