For God wanted them to know that the riches and glory of Christ are for you Gentiles, too. And this is the secret: Christ lives in you. This gives you assurance of sharing his glory. – Colossians 1:27
The secret is Christ living in you.
As in the real you, and not the fasçade you might be presenting to the world.
The power you carry within your Christ-nature is expressed when you are…you.
