**OF THE SACRAMENTS.**
When these things are explained singly and separately, they will be much clearer. Circumcision was a sign by which the Jews were reminded that whatever comes of the seed of man—in other words, the whole nature of man—is corrupt, and requires to be cut off; moreover, it was a proof and memorial to confirm them in the promise made to Abraham, of a seed in whom all the nations of the earth should be blessed, and from whom they themselves were to look for a blessing. That saving seed, as we are taught by Paul ( Gal. 5:16 ), was Christ, in whom alone they trusted to recover what they had lost in Adam. Wherefore circumcision was to them what Paul says it was to Abraham—viz. a sign of the righteousness of faith ( Rom. 9:11 ):—viz. a seal by which they were more certainly assured that their faith in waiting for the Lord would be accepted by God for righteousness. But we shall have a better opportunity elsewhere (chap. 16 sec. 3, 4) of following out the comparison between circumcision and baptism. Heb. 9:1-14 ; 1 John 1:7 ; Rev. 1:5 ; Heb. 4:14 ; 5:5; 9:11.
