How does God reveal our spiritual condition?

God reveals our spiritual condition primarily through the authority of Scripture and the work of the Holy Spirit in our hearts. In the case of Nicodemus, Jesus confronted him with truths about spiritual reality that Nicodemus was blind to, showcasing the necessity of being born again to perceive the kingdom of God (John 3:3). God's Word serves as a mirror that reflects our sinful nature and desperate need for His salvation. It's through this divine revelation, often coupled with conviction of sin, that we come to understand our true state before Him, prompting us to seek His mercy and grace for redemption.
