How do we know the importance of putting on the Lord Jesus Christ?

Putting on the Lord Jesus Christ, as urged in Romans 13:14, signifies the intentionality of living according to His character and purposes. This rather than simply going through the motions or being lukewarm in our faith. Paul's exhortation encourages believers to act according to their new identity in Christ — to think, speak, and live reflecting the attributes of Christ. This principle is not just theological; it holds practical implications for every aspect of our lives, compelling us to serve others, engage in ministry, and actively pursue God's glory in all endeavors. Thus, the act of 'putting on Christ' shapes our personal and communal lives within the body of believers.
