Isaac, like most of us, was not particularly worthy of God’s blessing. In fact, in Genesis 26:5 God says He will bless Isaac because of his father Abraham “who obeyed God and God’s requirements, commands, decrees, and laws.” This was long before God gave Moses and the Israelites the Ten Commandments and all the OT commandments and laws. Yet Abraham obeyed God and God’s commandments. Abraham walked so close to God he just knew what pleased Him. God tells Isaac in Verse 24 that he should not fear because God will be with him—again because of Abraham.
