"***** For His own name's sake, God will not permit the froward and the independent to carry out their unsanctified plans. He will visit them for their perversity of action. “There is no peace, saith my God, to the wicked.” Isaiah 57:21 . But in His judgments the Lord will remember mercy. He declares: 8T 219.1"
"There is no peace, saith my God, to the wicked."
EGW directly quotes Isaiah 57:21.
"Nevertheless my lovingkindness will I not utterly take from him, nor suffer my faithfulness to fail."
Both passages deal with God's mercy even in judgment. While not a direct quote, the sentiment expressed in Psalms 89:33 aligns with EGW's statement that 'in His judgments the Lord will remember mercy'.
