Romans 8:10 But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness.
There is a stark difference between those who have Christ living in them and those who do not. There is only life in those who are in the Spirit. While it may seem that people are alive because they’re walking around and doing things people do, inside those who don’t have Christ are dead. They’re the walking dead.
Something spectacular happens when you surrender your life over to Jesus Christ. God takes what was once dead and makes it alive (Ephesians 2:5). If you are His, He’s brought you to life because now it’s no longer you who live, but Christ in you (Galatians 2:20). Your body is just a vessel to hold the Spirit that lives in you and through you (2 Corinthians 4:7). It’s not your power or mine that do great things; it’s the power of God working.
You see, we can’t live holy and sinless lives that would enable us to have such power. That’s why it’s evident that it’s the righteousness of Christ that makes it possible. It’s Him that lived a perfect life, and He is the one who purchased our ransom. He is able to do far more than we could ever even think or begin to imagine (Ephesians 3:20) and He does it through us, the living.
