" Abraham had laid his son on the table of sacrifice, knowing that, were he to be killed, the entire hope for the future, all of God’s promises, would be gone (Gen. 22:1–14). He trusted God to overturn death itself to keep those promises. We are heirs then, the children of promise in Christ (Gal. 4:26–28). The promises were never made to DNA lines or to marked-out skin, but to a faithful remnant. That remnant turns out to be one man, Jesus of Nazareth, who joins in himself God and God-imaging humanity. Flesh and blood gave us our physical existence, but flesh and blood cannot inherit the kingdom of God. "
