King James Bible
"Now we, brethren, as Isaac was, are the children of promise."
Paul directly addresses fellow believers, using familial language to emphasize their shared spiritual kinship. The word 'now' marks a shift from his allegory of Sarah and Hagar to its present application for the Galatian church. Isaac serves as the prototype—born supernaturally through God's promise rather than human effort. Paul draws from Genesis where Isaac's birth came through divine intervention when Sarah was barren, contrasting with Ishmael's natural birth. Believers inherit their spiritual status through God's promise, not through law-keeping or physical descent. This designation places Christians in the lineage of faith rather than flesh, making them heirs of Abraham's blessing through grace.
