Why is seeking God's righteousness important?

Seeking God's righteousness is paramount according to Matthew 6:33, which instructs us to 'seek ye first the kingdom of God, and his righteousness.' This righteousness is not of our own, which Isaiah 64:6 describes as 'filthy rags.' Rather, it is the righteousness of Christ, which grants believers the status of being justified before God. Without this divine righteousness, which is given in Christ, we cannot enter the kingdom of heaven. Thus, understanding that our righteousness must come through faith in Christ is crucial for anyone aspiring to a true relationship with God and entry into His kingdom.
