How does God expose our sinful nature?

God employs various means to expose our sinful nature, primarily through His Word and the work of the Holy Spirit. In Isaiah 58:1, the Lord commands His prophet to cry aloud and show the people their transgressions. This divine revelation highlights the importance of God’s law and gospel in illuminating our flaws and leading us to the realization of our need for grace. Additionally, the Holy Spirit convicts us of sin, leading us to understand that our righteousness is devoid of merit before God. This exposure isn't punitive but merciful, aiming to direct us toward the grace offered in Christ.
