Why is focusing on Christ important for Christians?

In Colossians 3:1-2, Paul emphasizes the importance of setting our affections on things above rather than on earthly matters. This focus is vital because it aligns our thoughts and actions with our true identity in Christ rather than our sinful nature. By looking to Christ, we are reminded that our righteousness is found in Him alone, which liberates us from the burden of trying to achieve holiness through our own efforts. This Christ-centered focus aids in the mortification of sin, as true change comes from recognizing our union with Him in His death and resurrection and trusting in His power to transform us.
