You have voiced the same suffering, the sign of the same mystery, as has been voiced by almost all those who have been called upon to serve God. Even the Prophets of God, we know, suffered agony when the Spirit of God descended on Them and commanded Them to arise and preach. Look at Moses saying, "I am a stutterer!". Look at Muhammad rolled in His rug in agony! The Guardian himself suffered terribly when he learned he was the one who had been made the Guardian. So you see your sense of inadequacy, your realisation of your own unworthiness is not unique at all. Many, from the Highest to the humblest have had it. Now the wisdom of it is this: it is such seemingly weak instruments that demonstrate that God is the Power achieving the victories and not men. If you were a wealthy, prominent, strong individual who knew all about Africa and looked upon going out there as fun, any service you render, and victories you have, would be laid to your personality, not to the Cause of God! But because the reverse is true, your services will be a witness to the Power of Bahá’u’lláh and Truth of His Faith.
