Thou complainest thy heart is dead, wandering and contracted in duty: O, but remember Christ's blood speaks when thou canst not; it can plead for thee when thou art not able to speak a word for thyself. :Who is this that cometh out of the wilderness like pillars of smoke, perfumed with myrrh and frankincense, with all powders of the merchant?" Cant. 3:6. The prayers of Christians often go up before God sullied with their offensive corruptions; but remember, Christ "perfumes them with myrrh," by his intercession he gives them a sweet perfume.
The Fountain of Life by John Flavel (1628-1691)
