The Lily of the Valley anointing oil scent is inspired by the grace and limitless love offered by God to those who believe in Him. The term "lily" covered a wide variety of flowers ranging from colorful to the purest of white. It is probably the latter to which Jesus refers when He told us to "Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these" (Mt 6:28-29).
This lesson from our Lord is intended to teach the very great love and care available for those who trust in Him.
"I [am] the Rose of Sharon, [and] the lily of the valleys." (Song of Songs 2:1)
