“A sweet savor unto the Lord” is the hallmark language of the burnt and peace offerings. I believe it is only used one time with regard to the sin offering. When we consecrate our lives to God, when we decide to walk a sanctified walk, it is a well-pleasing aroma to Him. Our life ceases to have the repugnant stench of the unclean about it. Instead, it becomes a perfume He is pleased to inhale.
