"Those who were not my people I will call 'my people,' and her who was not beloved I will call 'beloved'” (v25). Paul explained that non-Jews could be “beloved,” part of God’s family by faith, because this was consistent with God’s ways. In the Old Testament, many Israelites missed out on fellowship with God because instead of responding to His miracles and gifts by trusting Him, they relied on their own righteousness. “They did not pursue it by faith, but as if it were based on works” (v32).
“They will be called, ‘sons of the living God’” (v26). We are God’s beloved children when we trust Him, receiving His gift of salvation by faith (John 1:12).
