Isaac - William Kelly - Bog

Isaac was the pattern of sonship, the child of promise, and as Abraham was its depository, elect, called out, blessed, and to be a blessing universally for the earth at the end, though himself looking higher by faith. Sovereign grace wrought as to both father and son. "For the promise that he should be heir of the world was not to Abraham or to his seed through law, but through the righteousness of faith."
