When Abram was ninety-nine years old the Lord appeared to Abram and said to him, “I am God Almighty; walk before me, and be blameless, 2 that I may make my covenant between me and you, and may multiply you greatly.” 3 Then Abram fell on his face. And God said to him, 4 “Behold, my covenant is with you, and you shall be the father of a multitude of nations. 5 No longer shall your name be called Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations. 6 I will make you exceedingly fruitful, and I will make you into nations, and kings shall come from you. 7 And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, to be God to you and to your offspring after you. 8 And I will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and I will be their God.” 9 And God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10 This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. 11 You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. 12 He who is eight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or bought with your money from any foreigner who is not of your offspring, 13 both he who is born in your house and he who is bought with your money, shall surely be circumcised. So shall my covenant be in your flesh an everlasting covenant. 14 Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.” - Gen 17:1-14

I. God wants a relationship with humanity

The Five Covenants and Their Promises
Adamic - that God will redeem humanity
Noahic - That God will not destroy the earth with water again
Abrahamic - Abraham would have a son,, that he would father nations, that all people will be blessed through his descendants, that he will have the promised land.
Mosaic - the nation of Israel would be treasured by God, a kingdom of priests, a holy nation.
Davidic - everlasting kingdom

II. God knows humanities weakness and forgetfulness - Genesis 17:9-11

The Five Covenants and Their Signs
Adamic - being clothed (the first sacrifice to atone for sin)
Noahic - The Rainbow

Mosaic - The Ark of the covenant
Davidic - the temple
Symbolism of Circumcision:

III. God wants a relationship with you, and he knows your weakness.

Salvation was never from works, it has always been God’s work and he has given us a sign so we can know and remember.

28 For no one is a Jew who is merely one outwardly, nor is circumcision outward and physical. 29 But a Jew is one inwardly, and circumcision is a matter of the heart, by the Spirit, not by the letter. His praise is not from man but from God. – Romans 2:28-29

23 But the words “it was counted to him” were not written for his sake alone, 24 but for ours also. It will be counted to us who believe in him who raised from the dead Jesus our Lord, 25 who was delivered up for our trespasses and raised for our justification. – Romans 4:23-25

31 “Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah, 32 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. 33 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. 34 And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.” – Jeremiah 31:31-34

1 What shall we say then? Are we to continue in sin that grace may abound? 2 By no means! How can we who died to sin still live in it? 3 Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? 4 We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. – Romans 6:1-4

Our hyper fixation on moralistic living is coming from the same heart of relying on Circumcision for salvation. We can be a ‘good person’ and still be condemned to hell.

7 You were running well. Who hindered you from obeying the truth? 8 This persuasion is not from him who calls you. 9 A little leaven leavens the whole lump. 10 I have confidence in the Lord that you will take no other view, and the one who is troubling you will bear the penalty, whoever he is. 11 But if I, brothers,[b] still preach[c] circumcision, why am I still being persecuted? In that case the offense of the cross has been removed. 12 I wish those who unsettle you would emasculate themselves! – Galatians 5:7-12

13 And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, 14 by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. 15 He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him. – Colossians 2:13-15
