Non Dispensational Salvation
Eternal salvation has always been the same in every time period and will always be the same in all future time periods.
Enternal Salvation is by grace alone through faith alone in Christ alone.
(Acts 4:10-12 [KJV])  Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole.  This is the stone which was set at nought of you builders, which is become the head of the corner.  Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved.
Jesus is The Word of God.
(Revelation of John 19:13 [KJV]) And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
Jesus and the Father are one.
(I John 5:7 [KJV]) For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.
A person gets saved by hearing the words of Jesus and believing on the Father.
(John 5:24 [KJV]) Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
Jesus Christ the same always.
(Hebrews 13:8 [KJV]) Jesus Christ the same yesterday, and to day, and for ever.
No one has ever been eternally saved by works. No one will ever be eternally saved by their works.
(Romans 3:20 [KJV]) Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin.
(Galatians 3:10-11 [KJV])  For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.  But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.
(Galatians 2:16 [KJV]) Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ, even we have believed in Jesus Christ, that we might be justified by the faith of Christ, and not by the works of the law: for by the works of the law shall no flesh be justified.
The scripture cannot be broken so this has to be true.
(John 10:35 [KJV]) If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
The scripture is sufficient to salvation.
1 Mary commeth to the Sepulchre. 3 So doe Peter and Iohn ignorant of the Resurrection. 11 Iesus appeareth to Mary Magdalene, 19 And to his Disciples. 24 The incredulitie, and confession of Thomas. 30 The Scripture is sufficient to saluation.
