What does the Bible say about revealing sin?

In Isaiah 58:1, God instructs His prophet to 'cry aloud, spare not,' meaning that the truth about sin must be proclaimed clearly and boldly. This revelation of sin is not about merely listing transgressions; it often addresses a misunderstanding of what true righteousness is. The people may appear religious and righteous, but God indicates that their perceived righteousness can be sinful if it is self-serving rather than God-honoring. The prophet's role is to help others see how their self-righteousness stands in stark contrast to the righteousness that comes from faith in Christ.
