What does the Bible say about self-justification?

Proverbs 18:17 teaches that the first account of a situation may seem just, but it can be misleading. Those who present their own case often do so with the intent to distort the truth, omitting details that may implicate them. This is especially evident in a spiritual context where sinners attempt to justify themselves before God, typically downplaying or ignoring their true sinful natures. The tendency to embellish or manipulate the truth stems from our sin nature, leading individuals to present an inaccurate portrayal of their intentions and actions.
