Therefore if any person is [ingrafted] in Christ (the Messiah) he is a new creation (a new creature altogether); the old [previous moral and spiritual condition] has passed away. Behold, the fresh and new has come – 2 Corinthians 5:17 (Amplified Bible)
The new creation is without a past. He’s a brand new species of being that never existed before. When the scripture above says, “Old things are passed away,” it means the old life; the old nature no longer exists.
Romans 6:4 tells us that “…as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.” What you have now is a new life altogether. According to the Scriptures, when Jesus died, you died with Him; when He was buried, you were buried with Him; now that He’s resurrected, you’ve also arisen with Him into a newness of life.
That’s why the Word admonishes us to “…put on the new man, which after God is created in righteousness and true holiness” (Ephesians 4:24). Your old nature was crucified with Christ. Sickness, poverty, failure and death are not a part of your new life in Christ.
Cease to lament your past because God doesn’t have the record of that life. Your new life begun the day you received Christ and confessed His Lordship over your life. Eternal life was at once imparted to your human spirit, and you became a new creation.
I have the supernatural life of God in me! The resurrection life is at work in my spirit, soul and body! I walk in this newness of life, having put on the new man in Christ, which after God is created in righteousness and true holiness!
