Now the Lord said to Abram, “Go from your country and your kindred and your father’s house to the land that I will show you. 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. 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.” (Genesis 12:1-3)
Some believe the Abrahamic Covenant to be unconditional, no action required by Abram/Abraham in that it was made while Abram was asleep (15:12). Others believe the covenant was conditioned on Abraham having to prepare for the covenant ceremony and follow it up with circumcision. If, on the other hand, one views the covenant as beginning in Chapter 12 where God commanded Abram to leave Haran (his comfort zone) before he would bless him, then it is conditional.
The Abrahamic Covenant had three parts: First, the Lord promised to give Abraham and his descendants a land (defined in chapter 15:18-20). Second, he promised he would bless Abraham and a great nation would come from him. And third, that Abraham and his descendants would be a blessing to all nations, that he, the Lord, would bless those who blessed Abraham’s descendants and curse those who cursed his descendants. Further, the Lord instituted circumcision of males as a sign of the covenant in chapter 17:10-14.
God made similar covenants to Isaac (26:3-4) under the condition he stay in the land and then to Jacob (35:11-13).
On this side of the cross, we see the blessing of Abraham coming through the peace and the abundant life offered through the death and resurrection of Jesus. Throughout Genesis and the Old Testament, the Lord blessed people who stood by, protected, and supported the children of Israel. History tells us that those who have come against Israel have been cursed. And then there is the judgement of the nations often viewed as those who support Israel (sheep) and those who do not (goats) (Matthew 25:31-46).
As believers, God calls us out of our comfort zone (sets us apart) into an assigned territory in which we are to serve and minister, be it large or small, as he desires, that is bless those around us through our gifts, talents, and skills. Have you left your comfort zone? What is your territory? Where has he called you to serve? Who are you blessing? Does the presence of the Spirit set you apart in language, behavior, and countenance?
There can be no doubt that the blessing, of which believers are heirs, is justification by faith; and that the promise, according to which they are heirs of this blessing, is the gospel promise made to Abraham. Adoniram Judson
