The superior excellency of Abel's sacrifice to Cain's, lay both in the matter and in the manner of it; the one was offered heartily to the LORD, the other only in show; the one was offered in Faith, the other not; Abel looked through his sacrifice to the Sacrifice of Christ, not so Cain. Abel's sacrifice was a lamb, a type of Christ, the Lamb of God; a firstling, a figure of Him Who is the Firstborn of every creature; one of the fattest of his flock, expressive of the excellency of Christ; and this was offered up at the end of days, as Christ at the end of the world; and the superior excellency of the sacrifice of the one to that of the other, appears from God's regard to the one, and not to the other, Genesis 4:5, from whence it may be observed, that sacrifices were of Divine Institution and were very early types of Christ and that there always were two sorts of worshippers, Spiritual and carnal ones, whom God can distinguish, for He seeth not as man seeth; that the acceptance of persons is in Christ and is previous to their offerings; that whatsoever works do not spring from Faith are unacceptable to God; that no dependence is to be had on birth privileges, or outward actions and that electing and distinguishing grace very early took place and appeared.
