Signs of Grace
In the course of time Cain brought to the LORD an offering of the fruit of the ground, and Abel also brought of the firstborn of his flock and of their fat portions.
Signs of Grace
It was a great comfort for Adam that, after he had lost Paradise, the tree of life, and the other privileges which were signs of grace, there was given to him another sign of grace, namely, the sacrifices, by which he could perceive that he had not been cast off by God but was still the object of God's concern and regard. This is what God was indicating when He kindled and consumed the sacrifices and offerings with fire from heaven, as we read about the sacrifice of Moses (Leviticus 9:24) and of Elijah (1 Kings 18:38). These were true manifestations of the divine mercy which the wretched people needed in order not to be without some light of the grace of God. In the same way the very Word, Baptism, and the Eucharist are our light-bearers today, toward which we look as dependable tokens of the sun of grace. We can state with certainty that where the Eucharist, Baptism, and the Word are, there are Christ, forgiveness of sins, and eternal life. . .. It is not the worth of the work itself that is of value in the sacrifice; it is the mercy and power of the divine promise, because God prescribes this form of worship and promises that it will be pleasing to Him. Therefore what Baptism and the Lord's Supper are for us, sacrifice and offering was for Adam after the promise.
