How do we know that Christ's righteousness is sufficient for us?

The sufficiency of Christ's righteousness comes from the transformative nature of His sacrifice and resurrection, which provides believers with an alien righteousness—one not derived from our works but credited to us by faith (Philippians 3:9). The preacher emphasizes that we are inherently unable to produce righteousness and that our attempts at righteousness are like "filthy rags" (Isaiah 64:6). Through faith, we receive Christ's perfect righteousness, which stands before God on our behalf and assures us of salvation and acceptance into His presence.
