Trustworthy

If a man were to perform every good work, yet fail in the least scruple to be entirely trustworthy and honest, his good works would become as dry tinder and his failure as a soul-consuming fire. If, on the other hand, he should fall short in all his affairs, yet act with trustworthiness and honesty, all his defects would ultimately be righted, all injuries remedied, and all infirmities healed. Our meaning is that, in the sight of God, trustworthiness is the bedrock of His Faith and the foundation of all virtues and perfections. A man deprived of this quality is destitute of everything. What shall faith and piety avail if trustworthiness be lacking? Of what consequence can they be? What benefit or advantage can they confer? Wherefore 'Abdu'l-Bahá counselleth the friends -- nay, rather, fervently imploreth them -- so vigilantly to guard the sanctity of the Cause of God and preserve their own dignity as individuals that all nations shall come to know and honour them for their trustworthiness and integrity.
