In just one chapter the life of Isaac runs parallel to the life of Abraham in it least half a dozen ways. One of the first is the confirmation of the covenant promises to Isaac. But thereâ€™s a twist. Isaac is told that the promises come to him â€śbecause Abraham obeyed my voice and kept my charge, my commandments, my statutes, and my lawsâ€ť (Genesis 26:5). Is this salvation by works? If not, then why are the covenant promises to Isaac seen as a reward for Abrahamâ€™s obedience. The answer is found in how Abraham himself is a type of the work of Christ.
