What did God promise Abraham about Sarah and Isaac?
God promised Abraham that Sarah his wife would indeed bear him a son, and that he must name the child Isaac. God further promised to establish His everlasting covenant with Isaac and with Isaac's seed after him. This was God's promise, and it would surely happen even if Abraham and Sarah lost sight of it.
Les explains that when Abraham asked God that Ishmael might live before Him, God answered that Sarah his wife would bear a son indeed, and Abraham was to call his name Isaac. Les points out that this is a promise because God said 'I will.' Even though Abraham and Sarah may have lost sight of it, it was still God's promise and it was going to happen. Les also notes that God said He would establish His covenant with Isaac for an everlasting covenant, and with his seed after him. Les connects this to God's promises concerning Israel, who will yet receive the kingdom because God has said it.
And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him.
