What is the Gospel?
(1) Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
(2) By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
(3) For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
(4) And that he was buried, and that he rose again the third day according to the scriptures:
What does the Gospel do?
Rom 1:16 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
How is salvation attained?
Rom 6:23 For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
What saves under Calvin's system?
God does not base His election on anything He sees in the individual. He chooses the elect according to the kind intention of His will (Eph. 1:4-8; Rom. 9:11) without any consideration of merit within the individual. Nor does God look into the future to see who would pick Him. Also, as some are elected into salvation, others are not (Rom. 9:15, 21).
No mention of the blood of Christ, the death, burial, and resurrection of Christ.
And you won't find these things mentioned in most outlines of the five points of Calvin.
They will often mention the death of Christ under “Limited atonement”, but only the fact that it isn't sufficient for all – some will say effective for all, but they twist that too.
Now John, I don't know about you, but my salvation is based on the free gift of salvation through the shed blood of Christ, and was attained by me by grace through faith.
Any other way of salvation is another Gospel, which is not another.
Therefore to do as the Calvinist does and base salvation, not on the blood of Christ, but upon the choice of God, is another Gospel which is not another.
I believe that many people amongst Calvinistic churches are fooled by the doublespeak of the Calvinist teachers, and have actually believed the surface preaching without understanding the redefinition of words that they use.
But anyone who actually understands and follows Calvin's teachings, is basing their salvation on something other than the blood of Christ.
And that means that they are not saved.
Act 4:12 Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
Calvinists are like many other cults – they redefine words, jump through linguistic hoops, and make leaps of logic all so that they can re-understand what the Bible says.
But if you base your salvation on anything other than the blood of Christ, you are not saved.
And the Calvinist bases his salvation on the choice of God not the blood of Christ.
