Isaiah 63:8

God had elected Israel as His son. This was not due to anything in Israel but totally due to God’s loving selection of Abraham and his descendants for special blessing (cf. 1 Corinthians 15:9-10). God had a right to expect that the nation, so chosen, would respond with loyalty and integrity toward Him. This mutual commitment would have resulted in God delivering His people whenever they needed salvation. Note that the result would not be God insulating the Israelites from difficulties but delivering them from them.
