Isaiah portrays God’s oncoming judgment as a “consuming fire” (Isaiah 1:31; 30:33). At the same time, Isaiah understands that God is a God of mercy, grace, and compassion (Isaiah 5:25; 11:16; 14:1-2; 32:2; 40:3; 41:14-16). The nation of Israel (both Judah and Israel) is blind and deaf to God’s commands (Isaiah 6:9-10; 42:7). Judah is compared to a vineyard that should be, and will be, trampled on (Isaiah 5:1-7).
Wakati huo huo, Isaya anaelewa kuwa Mungu ni Mungu wa rehema, neema, na huruma (Isaya 5:25; 11:16; 14: 1-2; 32: 2; 40: 3; 41: 14-16). Taifa la Israeli (Yuda na Israeli) ni kipofu na kiziwi kwa amri za Mungu (Isaya 6: 9-10; 42: 7). Yuda inalinganishwa na shamba la mizabibu ambalo lazima, na itakuwa, litakanyagwa (Isaya 5: 1-7). Tu kwa sababu ya huruma yake na ahadi zake kwa Israeli, Mungu hataruhusu Israeli au Yuda kuangamizwa kabisa.
