Today’s OT reading has us with a very concerned Abram and Sarai. Just turn back to Genesis 12:1-9 and you will see exactly what I mean. Abram has left everything to follow this call from God. He has packed up His family has left everything familiar and was told:

“Go from your country and your kindred and your father’s house to the land that I will show you. 2 And I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing. 3 I will bless those who bless you, and him who dishonors you I will curse, and in you all the families of the earth shall be blessed.”

I have read that families did not do this type of thing. To say it was counter-cultural would be a gross understatement. Everything rested on your family. There were no governments or laws to protect you. All you had was your family. At any given moment, someone could come to enslave you, rob you or even wipe your entire family off the face of the earth. So for Abram to leave was to do more than relocate and miss Christmas meals, it was to separate himself from his fathers wealth, his families protection and everything he has ever known. Not to mention he wasn’t a young and naive 18 year old running to New York. He was 75 years old and this is all he has ever known. Add to that he is taking along his wife for this journey only adds to the anxiety he must have felt.

But today’s reading puts us 25 years later. And if you haven’t noticed, Sarai is still barren and this promise seems to be fading at an alarming rate. Abram is 100 years old, Sarai is 90 years old (we find this out later) and there seems to be no significant change to validate this promise that Abram has heard.

Then God comes and reaasures Abram. He revalidates His promises but this time takes it a step further. Upon this reassurance we see Abram beliving God and him being “justified” by faith. This will become one of the most important words in your New Testament and if you read anything about theology this is an issue facing the church today. It was because of Abrams faith that God made Him righteous, yet he produced the fruit of faith by leaving all he knew to follow the call of God.

Shortly after that God then enters into a unilateral covenant thus sealing Abram’s justification (Romans 4) and guaranteeing His promise. In spite of Abram’s righteousness, faith and the covenant being ratified by God Himself. Abram still sins against the Lord. He attempts to give God a child instead of God giving him a child. In spite of this God shows His faithfulness to His own covenant by giving both Abram and Sarai new identities by changing their names and even in their unfaithfulness Abram’s offspring is blessed.

Today how many of us, after being called away from everything we knew and loved and lived for, given new names, new identities still do not trust God? Yet in spite of all of our lack of trust, God is still faithful to bring His promises to pass. Today you and I are aliens in a foregin land. The Gospel has brought us into a new relationship with new identies and a new destination yet often times our circumstances blinds us on the road much like Abraham’s circumstance blinded him. I remember reading Pilgrims Progress and sometimes Christian would turn the wrong way and find himself in some difficult circumstances, yet in spite of that God was bringing Him to the celestial city.

We have to understand that in spite of all we see in our own circumstances and the failure we experience,  God’s unilateral covenant has been ratified in the death, burial and resurrection of Jesus Christ. Just like Abraham was justified by faith we too have been justified by faith. Just like Abraham was given a sign/seal of the covenant which was circumcision we too have been given a sign/seal of the covenant and He is the Holy Spirit which produces a new heart. And as with Sarah, God does not need our assistance in bringing His promises to pass, He only wants us to yield to Him. What God began He will complete. Romans 8:28-30 gives us a wonderful promise of God’s faithfulness to His covenant people. We can rest assured that we will be what He wants us to be, though we can make this journey rough for ourselves (you will see that Ishmael will become a problem to the promised seed).

Our new testament reading is also an introduction to a covenant. This covenant is called the “New Covenant”. Jesus in the sermon of the mount is beginning to lay the ground work for this covenant. He is the master builder, a new law giver and is now calling His people to a new moral standard. It is a moral standard built on the motivation of the heart not the letter of the law. We will later come to find out that just like the covenant with Abraham, it will be a gracious covenant. This covenant will be based on faith and upheld by God. There will be fruit requirement as evidence that we are part of this covenant and we see that in what Jesus is calling us to do, just like the fruit of Abraham’s faith was him leaving his father, but just like Abraham it will not be conditional. God will see that all He promised to Abraham come to fruition and Jesus will see that all He promised to His covenant people will come to fruition!
