“For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.” (Hebrews 9:26 KJV)
When Jesus was on the cross He cried out “IT IS FINISHED”. In Greek this means “PAID IN FULL”. Jesus did not pay for sins only in the past. If that were true yours and my sins would not even qualify because we are all in the future of the time of the cross. NO no no. Jesus paid for the sins of THE WHOLE WORLD and whosoever will believe and accept the FREE gift of eternal life have been 100% forgiven all the sins of their entire life (past/present/future).
“Blessed be the God and Father of our Lord Jesus Christ, who hath blessed us WITH ALL spiritual blessings in heavenly places in Christ: According as he hath chosen us in him BEFORE THE FOUNDATION OF THE WORLD, that we should BE HOLY and WITHOUT BLAME before him in love: Having predestinated us unto the adoption of children by Jesus Christ to himself, according to the good pleasure of HIS WILL,To the praise of the glory of HIS grace, wherein HE HATH MADE US ACCEPTED in the beloved.” (Ephesians 1:3-6 KJV)
“For then must he often have suffered since the foundation of the world: but now ONCE in the end of the world hath he appeared to PUT AWAY sin by the sacrifice OF HIMSELF.” (Hewbrews 9:26 KJV)
In Colossians 2:13-14 it states,
“And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you ALL trespasses; BLOTTING OUT the handwriting of ORDINANCES that was against us, which was contrary to us, and took it OUT OF THE WAY, nailing it to his cross;”
The Greek word translated all in this passage is pas (Strong’s G3956). It means ‘individually, each, every, any, all, the whole, everyone, all things, everything collectively’. This supports the fact that all sins past present and future were forgiven at the cross. And it agrees completely with other Scriptures below.
“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 (in Greek means ‘downpayment’) of our inheritance until the redemption of the purchased possession, unto the praise of his glory.” (Ephesians 1:13-14 (brackets added for incite) KJV)
We see this clearly again in this passage of Scripture,
“Now he which stablisheth us with you in Christ, and hath anointed us, is God; Who hath also SEALED US, and given the earnest(in Greek means ‘down payment’) of the Spirit in our hearts.” (2 Corinthians 1:21-22 (brackets added for incite) KJV)
Jesus offered Himself as a once for all time sacrifice for sin that has made us perfect forever. Forever means what? Well, it means FOREVER! Never to be lost! And then He sat down on the right hand of God. It is finished!
“But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; From henceforth expecting till his enemies be made his footstool. For by one offering he hath perfected for ever them that are sanctified.” (Hebrews 10:12-14 KJV)
Look what Paul tells us,
“Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.” (2 Corinthians 5:17 KJV)
No, Salvation cannot be lost but rewards at Bema Seat can be. You see, as Paul taught us, God has separated the sin from the sinner at the very moment of our Salvation when he wrote:
“For I know that in me (that is, in my flesh,) dwelleth NO GOOD THING: for to will is present with me; but how to perform that which is good I FIND NOT. For the good that I would I do not: but the evil which I would not, that I do. Now if I do that I would not, it is no more I that do it, BUT SIN THAT DWELLETH IN ME.” (Romans 7:18-20 KJV)
The sin that dwells in us is called ‘the flesh’ and it remains in us until our full and COMPLETE perfection when we receive our new immortal bodies at The Rapture. Until then we have the Holy Spirit within us as our down payment and assurance of our future perfection.
Salvation cannot be lost if it is Salvation the Biblical way and not what men may teach. Salvation is not by good works, being a good person nor following religious rituals. Read your Bible in proper context and it is clear, Salvation cannot be lost once you are in Christ.
