What does ignorance of God's righteousness mean?

Ignorance of God's righteousness means that individuals are unaware of their true spiritual state and the holiness of God. Romans 10:3 highlights that many have a zeal for God but are misguided, attempting to establish their own righteousness instead of submitting to God's. This ignorance stems from a failure to grasp the gravity of sin and the holiness of God, which the law demands. Without recognizing God's holiness, individuals mistakenly rely on their own good works for salvation, which is insufficient. True understanding begins when one acknowledges their need for the imputed righteousness found in Christ alone, leading to genuine faith and salvation.
