“Have you not sins of your own against the LORD your God?” (28:10). After a brief time under the righteous king Jotham (ch 27), Judah was ruled by wicked Ahaz, who worshipped idols and sacrificed his own children (28:3-4). Ahaz’s sins led to Judah’s downfall, and they were defeated by both Syria and northern Israel (v5). However, God warned through a prophet that northern Israel, although victorious, did not have the right to enslave their relatives in Judah (28:10-13).
“For our guilt is already great” (28:13). Someone else’s sin never justifies our own wrong actions. God calls us to repentance and the real pursuit of holiness, not self-righteousness.
