There is need of the voice crying in the wilderness, that the soul, forsaken by God, may be recalled to making straight the way of the Lord, following no more the crooked paths of the serpent. This has reference both to the contemplative life, as enlightened by truth, without mixture of falsehood, and to the practical, as following up the correct perception by the suitable action. Wherefore he adds, Make straight the way of the Lord, as saith the prophet, Esaias.
