Colossians 3:1-3 (NKJV)
There are a lot of things that we can use to identify ourselves. Many people have a passport, a driver's license, an identity card, or something else that they can use to show who they are. The same thing is true for us as Christians, we have something we can use to show who we are and to identify ourselves. We are not just who we were born as naturally with the identity of a man or woman from some country with some ethnic background. When we become born again we get a whole new identity and our new identity is found in Christ.
Some people base their identity on the family they come from, the color of their skin, their educational or economic standing, or some other external factor. But, for those who have accepted Jesus Christ as their Lord and Savior we now have a new identity. The Bible tells us in Colossians 3 that we need to have our attention focused on heavenly, spiritual realities because our life, who we really are, is hidden in Christ. What is even better than this is that our new identity is described to us throughout the New Testament so we have an easy way to learn all about who we really are.
The Bible tells us that we are new creations in Christ, the old is gone and the new has come (2 Corinthians 5:17). No matter what you have done in the past, good or bad, you have a new start with God in Christ. We read in 2 Corinthians 5:21 that we are now the righteousness of God in Christ, we have the same right standing with God that Jesus does! These are just a few of the things about who we really are in Christ. We need to learn about our true identity from God's Word and know who we are in Christ. Once we know who we really are it will change how we live and help us to change the world!
