What does it mean that we are now adorned with Christ's righteousness?

In Ezekiel 16:8-14, there is a beautiful depiction of how God adorns His people with His righteousness. We are told that He 'decked thee also with ornaments' and beautified us. This signifies that, as believers, we are covered by the righteousness of Christ, which is imputed to us through faith. Paul writes in 2 Corinthians 5:21 that 'He made Him to be sin for us, who knew no sin; that we might be made the righteousness of God in Him.' This means that our standing before God is based not on our works, but on the accomplished work of Christ, which brings us acceptance and eternal life.
