Contradiction with Proverbs 16:9
While Isaiah 26:12 acknowledges that God ordains peace, Proverbs 16:9 suggests man's heart directs his path, implying human agency rather than divine determination.
Proverbs 16:9: A man's heart deviseth his way: but the LORD directeth his steps.
Contradiction with Jeremiah 10:23
Isaiah 26:12 indicates God establishes peace for us, whereas Jeremiah 10:23 states that it is not in man's way to direct his steps, implying reliance on God's guidance conflicts with the idea of human-directed outcomes.
Jeremiah 10:23: O LORD, I know that the way of man [is] not in himself: [it is] not in man that walketh to direct his steps.
Contradiction with Psalm 127:1
This verse suggests the efforts of those without God's blessing are in vain, differing from Isaiah 26:12’s assurance of God’s ordained peace irrespective of human actions.
Psalm 127:1: [A Song of degrees for Solomon.] Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh [but] in vain. [for...: or, of Solomon] [that...: Heb. that are builders of it in it]
Contradiction with Romans 8:28
While Isaiah 26:12 speaks of peace ordained by God, Romans 8:28 emphasizes all things (not just peace) work for good to those who love God, suggesting a broader providential oversight.
Romans 8:28: And we know that all things work together for good to them that love God, to them who are the called according to [his] purpose.
