How can I stand before God as a sinful person?

The question of how a sinful person can stand before a holy God is essential in Reformed thought. The sermon asserts that we cannot approach God's holiness on our own merit because we are guilty of sin. However, Christ, being the only perfect One, ascended the hill of the Lord with clean hands and a pure heart. As believers, we stand in Him; His righteousness is imputed to us through faith. Our union with Christ is what allows us to approach God without fear, as we are declared righteous on account of Christ's work, fulfilling the demands of justice on our behalf.
