David Wilkerson emphasizes that true righteousness, which is the only kind accepted by God, comes solely through faith in Jesus Christ. He illustrates this by referencing Noah, who became an heir of righteousness not through his actions but through his faith and belief in God's revelation. Wilkerson reminds us that Jesus left us a profound inheritance of perfect righteousness, enabling us to stand before God uncondemned, despite our inability to fulfill the law ourselves. This inheritance is far more valuable than any earthly riches, as it is rooted in God's mercy and grace. Ultimately, it is the Holy Spirit that empowers believers to live out this righteousness credited to them.
