We are eternally saved by putting out trust in the shed blood of Christ.
Paul is a minister of Jesus Christ to the gentiles.
 Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand;
 By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.
 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;
 And that he was buried, and that he rose again the third day according to the scriptures:— KJV, 1 Corinthians 15:1-4
And it is by Pauls gospel that we shall be eternally judged.
In the day when God shall judge the secrets of men by Jesus Christ according to my gospel. — KJV, Romans 2:16
 That we should be to the praise of his glory, who first trusted in Christ.
 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.— KJV, Ephesians 1:12-14
Blood of Christ
We are not saved by the death of Christ. We are saved by his blood.
Put your trust in the shed blood of Christ for your salvation.
And almost all things are by the law purged with blood; and without shedding of blood is no remission. — KJV, Hebrews 9:22
 But Christ being come an high priest of good things to come, by a greater and more perfect tabernacle, not made with hands, that is to say, not of this building;
 Neither by the blood of goats and calves, but by his own blood he entered in once into the holy place, having obtained eternal redemption for us.— KJV, Hebrews 9:11-12
Whom God hath set forth to be a propitiation through faith in his blood, to declare his righteousness for the remission of sins that are past, through the forbearance of God; — KJV, Romans 3:25
In whom we have redemption through his blood, even the forgiveness of sins: — KJV, Colossians 1:14
In whom we have redemption through his blood, the forgiveness of sins, according to the riches of his grace; — KJV, Ephesians 1:7

 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.— KJV, Ephesians 2:8-9
