In this pamphlet I have sought to provide a Biblically based description of Christian worship—what it is and the principles that should guide us. Affection for the Father and the Son leads to worship, but it should be accompanied with intelligence in divine things. Mary of Bethany had an affection governed by spiritual intelligence. We see an expression of worship in the twelfth chapter of John’s gospel: “Then took Mary a pound of ointment of spikenard, very costly, and anointed the feet of Jesus, and wiped His feet with her hair: and the house was filled with the odour of the ointment” (John 12:3). Not a word was spoken by Mary—praise is always audible, but worship is not necessarily so. We do not find Mary at the cross nor at the empty tomb. She had an intelligence that neither her sister Martha nor the disciples had. With Mary Magdalene we see divine affection (never should we imagine it was merely human) but there was not that same degree of spiritual comprehension. “Mary [Magdalene] stood without at the sepulchre weeping: ... And [the angels] say unto her, Woman, why weepest thou? She saith unto them, Because they have taken away my Lord, and I know not where they have laid Him” (John 20:11, 13). We do not gain either—divine affection nor intelligence in divine things—except by spending time in the presence of the Lord, enjoying communion with Him, and by reading His word. It is noteworthy, therefore, that we find Mary of Bethany three times at the Lord’s feet: first in hearing His word (Luke 10:39), next in supplication (John 11:32), and finally in worship (John 12:3).
