What is true of all sacrifices is true of the sacrifice of Christ. It remains invalid and of none effect to those who do not through it yield themselves to God. Sacrifices were intended to be the embodiment and expression of a state of feeling towards God, of a submission or offering of men's selves to God; of a return to that right relation which ought ever to subsist between creature and Creator. Christ's sacrifice is valid for us when it is that outward thing which best expresses our feeling towards God and through which we offer or yield ourselves to God. His sacrifice is the open door through which God freely admits all who aim at a consecration and obedience like to His. It is valid for us when through it we sacrifice ourselves. Whatever His sacrifice expresses we desire to take and use as the only satisfactory expression of our own aims and desires. Did Christ perfectly submit to and fulfil the will of God? So would we. Did He acknowledge the infinite evil of sin and patiently bear its penalties, still loving the Holy and Righteous God? So would we endure all chastening, and still resist unto blood striving against sin. (2) Again, we here find a very sharp and clear statement of the welcome truth, that continuance in sin is never a necessity, that God points the way out of sin, and that from the first He has been on man's side and has done all that could be done to keep men from sinning. Observe how He expostulates with Cain. Take note of the plain, explicit fairness of the words in which He expostulates with him--instance, as it is, of how absolutely in the right God always is, and how abundantly He can justify all His dealings with us. God says as it were to Cain; Come now: and let us reason together. All God wants of any man is to be reasonable; to look at the facts of the case. "If thou doest well, shalt thou not (as well as Abel) be accepted? and if thou doest not well, sin lieth at the door," that is, if thou doest not well, the sin is not Abel's nor any one's but thine own, and therefore anger at another is not the proper remedy, but anger at yourself, and repentance.
