Salvation happens at a moment in time and a person is translated from being identified as unrighteous, to having the very righteousness of God, in Christ.
“For he hath MADE him to be sin for us, who knew no sin; that we might be MADE the righteousness of God in him.” (2 Corinthians 5:21 KJV)
The believer’s identity is no longer an UNRIGHTEOUS person. He has been MADE a RIGHTEOUS person by God.
Salvation Is About A Change Of Position Before God
A Change of position from an unrighteous nature to a righteous nature.
If an unbeliever renounces his identity as an unrighteous sinner, he can never be righteous even if he renounces his sinner identity. The Bible is clear that all have sinned and fallen short of the Holiness of God. It matters not if a person renounces being a sinner. Their sins will one day need to be paid for. This is a true statement yes?
And now, after a person believes on Christ, they become a NEW CREATED SPIRIT. A direct creation of God, fully righteous and redeemed. Is this by our own efforts? No. Apostle Paul wrote,
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.” (Epehsians 2:8-9 KJV)
And earlier in Ephesians Paul writes,
“In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory.” (Ephesians 1:13-14 KJV)
Now SEALED for eternity by the Holy Spirit this person has passed from death to life (John 5:24). Salvation is ETERNAL (John 3).
Now this believer has become a Son of God. (a term used in the Bible only for direct created beings such as Angels and Adam.) The believer has Two natures now, The Flesh Sin Nature and the Newly Created Spirit. This Spirit is now the new eternally and POSITIONALLY RIGHTEOUS US as we were translated to the identity of being righteous by God. (Romans 7, 2 Corinthians 5:21)
So this statement is also true of a believer:
If an believer renounces his identity as an righteous person, he can never be unrighteous even if he renounces his righteousness of God (in Christ) identity.
The Bible has two camps of people…
RIGHTEOUS and UNRIGHTEOUS
or REDEEMED and UNREDEEMED.
We did nothing in our own effort to be part of the righteous camp. We are not righteous because of our efforts. It was Christ’s atonement and our belief in this grace gift of God that translated us INSTANTLY at the moment of belief to being positionally righteous and redeemed.
God’s love is so vast for us unconditionally. Jesus’ ONCE FOR ALL sacrifice (Hebrews 10) is so powerful and binding it is just hard to believe but from what I see in Scriptures – it’s true.
Once God makes a person a New Creation in the Spirit and a son/daughter in the family of God… that person is there forever. God keeps His word – even of we do not.
