In chapter iv. 32-v. 2 the Father’s love and the Son’s self-sacrifice are spoken of in terms precisely parallel. They are altogether one in quality. Christ does not by His sacrifice persuade an angry Father to love His children; it is the Divine compassion in Christ that dictates and carries into effect the sacrifice. At the same time it was “an _offering_ and a _sacrifice_ to God.” God is love; but love is not everything in God. Justice is also Divine, and absolute in its own realm. Law can no more forgo its rights than love forget its compassions. Love must fulfil all righteousness; it must suffer law to mark out its path of obedience, or it remains an effusive, ineffectual sentiment, helpless to bless and save. Christ’s feet followed the stern and strait path of self-devotion; “He humbled Himself and became obedient,” He was “born under law.” And the law of God imposing death as the penalty for sin, which shaped Christ’s sacrifice, made it acceptable to God. Thus it was “an odour of a sweet smell.” Hence the love which follows Christ’s example, is love wedded with duty. It finds in an ordered devotion to the good of men the means to fulfil the all-holy Will and to present in turn its “offering to God.” Such love will be above the mere pleasing of men, above sentimentalism and indulgence; it will aim higher than secular ideals and temporal contentment. It regards men in their kinship to God and obligation to His law, and seeks to make them worthy of their calling. All human duties, for those who love God, are subordinate to this; all commands are summed up in one: “Thou shalt love thy neighbour as thyself.” The apostle pronounced the first and last word of his teaching when he said: _Walk in love, as the Christ also loved us._ 6. Above all others, one sin stamped the Gentile world of that time with infamy,--its _uncleanness_. St Paul has stigmatized this already in the burning words of verse 19. There we saw this vice in its intrinsic loathsomeness; here it is set in the light of Christ’s love on the one hand (ver. 2), and of the final judgement on the other (vv. 5, 6). Thus it is banished from the Christian fellowship in every form--even in the lightest, where it glances from the lips in words of jest: “Fornication and all uncleanness, let it not even be named among you.” Along with “filthiness, foolish talk and jesting” are to be heard no more. Passing from verse 2 to verse 3 by the contrastive _But_, one feels how repugnant are these things to the love of Christ. The perfume of the sacrifice of Calvary, so pleasing in heaven, sweetens our life on earth; its grace drives wanton and selfish passions from the heart, and destroys the pestilence of evil in the social atmosphere. Lust cannot breathe in the sight of the cross.
