We have it from God that there is Israel by descent from Abraham and then there are children of Abraham by virtue of being children of God's promise. John 8 shows these are distinct. Jesus has the same command to both: to love God and thus to love Him. John's epistles show a new command too: to obey the truth. I submit that the truth to obey is this: that the Abrahamic promise relates to children of the promise and to bless the children of the promise is to bless Jesus and the Abrahamic promise is then that those who do so will be blessed.
