What does Colossians 2:10 mean?
Here, Paul continues a thought he began in verse 9. The "whole fullness of deity" dwells in Jesus, meaning He is both entirely man and entirely God. Paul now links that "filling" to the way Christ relates to Christian believers. Jesus serves as the connection between the believer and God the Father. He is the way, the truth, and the life (John 14:6), the only way of salvation (Acts 4:12). The Colossian believers had been "filled with the knowledge of his will" (Colossians 1:9).Paul also re-emphasizes the supremacy of Jesus. Christ had authority to forgive sins (Matthew 9:6), to heal, and to cast out demons. All authority on heaven and earth has been given to Him (Matthew 28:18). All human authority has been appointed by God and is under His jurisdiction (Romans 13:1–2). Paul wrote in Ephesians 1:21 that Christ is "far above all rule and authority and power and dominion, and above every name that is named, not only in this age but also in the one to come."
Colossians 2:6–15 describes Christ's superiority in defeating sin. This is shown in stark contrast to the failure of the unbelieving world. Paul encourages the Colossians not to be tricked by deceptive arguments. This passage also explains the drastic nature of salvation. Those who put their faith in Christ are ''spiritually'' circumcised and are identified with God through their faith. This act of forgiveness by God frees us from the eternal penalty of sin, restores our relationship, and defeats the evil forces fighting against us.
In this passage, Paul warns Christians not to be taken in by deceptive arguments. These claims are attractive, but are merely tricks: they sound true, but they are not. Arguing for self-denial, legalism, visions, and other practices only looks good to observers. None of these are the real source of spiritual growth. Paul emphasizes the way Christ accomplished everything we need to be justified before God. As a result, there is no reason for believers to pursue these false, shallow ''shadows.'' We have the real substance: Jesus, so we should follow Him.
