The remaining part of the ritual was, as we have pointed out, peculiar to the burnt offering. In it alone the whole of the sacrifice was consumed on the altar, with the exceptions of the skin, which was given to the priest, and of the contents of the intestines. Hence it was sometimes called 'a whole burnt offering.' The meaning of this provision may be apprehended if we note that the word rendered 'burn,' in verse 9, is not that which simply implies destruction by fire, but is a peculiar word, reserved for sacrificial burnings, and meaning 'to cause to ascend in smoke or vapour.' The gross flesh was, as it were, refined into vapour and odour, and went up to God as 'a sweet savour.' It expressed, therefore, the transformation of the sinful human nature of the worshipper, by the refining power of the fire of God, into something more ethereal and kindred with the heaven to which it rose. Or, to put the thought in plainer words, on the basis of expiation, the glad surrender of the whole being is possible and will ensue; and when a man yields himself in joyful self-surrender to the God who has forgiven his sins, then the fire of the divine Spirit is shed abroad in his heart, and kindles a flame which lays hold on all the gross, earthly elements of his being, and changes them into fire, kindred with itself, which aspires, in ruddy tongues of upward-leaping light, to the God to whom the heart has been surrendered, and to whom the whole being tends.
This is the purpose of expiation; this is the summit of all religion. One man has realised to the full, in his life, what the burnt offering taught as the goal for all worshippers. Jesus has lived in the constant exercise of perfect self-surrender, and in the constant unmeasured possession of 'the Spirit of burning,' with which He has come to baptize us all. If we look to Him as our expiation, we should also find in Him the power to yield ourselves 'living sacrifices,' and draw from Him the sacred and refining fire, which shall transform our grossness into His likeness, and make even us 'acceptable to God, through Jesus Christ.'
