Circumcision the Sign of the Covenant

171 When Abram was ninety-nine years old, the Lord appeared to Abram and said to him, "I am Almighty God; walk before Me and be blameless. 2 And I will make My covenant between Me and you, and will multiply you exceedingly." 3 Then Abram fell on his face, and God talked with him, saying:

4 "As for Me, behold, My covenant is with you, and you shall be a father of many nations. 5 No longer shall your name be called Abram, but your name shall be Abraham; for I have made you a father of many nations. 6 I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you.

(Read Genesis 17:1-6)

The covenant was to be accomplished in due time. The promised Seed was Christ, and Christians in him. And all who are of faith are blessed with faithful Abram, being partakers of the same covenant blessings. In token of this covenant his name was changed from Abram, "a high father," to Abraham, "the father of a multitude." All that the Christian world enjoys, it is indebted for to Abraham and his Seed.
