"Now if Christ does live within you his presence means that your sinful nature is dead, but your spirit becomes alive because of the righteousness he brings with him." Romans 8:10
To state it more explicitly: The righteousness of Jesus murders the sinful nature and breathes life - HOOOO - into the human spirit. Have you heard the big impressive theological word, "sanctification," before? Simply put, it means "becoming holy" or "being made holy." Yet it's in how we approach that process - actually being sanctified - that you'll find some of the greatest margin for error in all of Christianity. For many, it becomes a religious slog perfectly akin to the way the Pharisees were trying to live out the commands and rules of the Old Covenant right in front of Jesus Himself.
That's not supposed to be us!
Instead, with perfect righteousness already living inside you - His name is Jesus, pleased to meet you! - it's your Abiding in Him, your moment-to-moment experience of His life that can't fail to win your obedience and, with it, your sanctification unto holiness. My friends, Jesus can't fail to be holy. Brothers and Sisters, let's not fail to enjoy and Abide in Him today!
