How do we know Christ's fullness includes all of God's attributes?

In Colossians 2:9, we are informed that 'For in him dwelleth all the fullness of the Godhead bodily.' This allows believers to access the entirety of God's attributes—His holiness, love, wisdom, and righteousness—through Christ. Jesus performs the works of God, revealing His divine nature; what He does is reflective of who He is. The indwelling of the fullness of God in Christ means that we can trust in Him for all aspects of our faith and life. Furthermore, this fullness assures us that through our union with Him, we receive all that pertains to life and godliness.
