While technically there are four aspects of salvation (Provisional Atonement, God’s grace, Sanctification, and Glorification - See
here) there are only two aspects of salvation we as believers need to be primarily concerned with in this life.
For the Bible teaches:
1st aspect of salvation:
Ephesians 2:8-9
8 “For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
9 Not of works, lest any man should boast.”
2nd aspect of salvation:
2 Thessalonians 2:13-14
13 “…God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth:
14 Whereunto he called you by our gospel,…”
This is not Calvinism by any means. Man has free will to either accept or reject God, but this happens when God illuminates the truth to a person at the right time or times in their life (Under the drawing of Christ and the conviction of the Spirit). For even Lydia’s heart was opened to understand Paul’s message. In other words, a person cannot believe without the working of God in their life to make that happen. But a person will know of the truth at the right time God chooses them to know the truth. It is up to the individual if they accept or reject the truth (See: 2 Thessalonians 2:10).
But there is only two steps we need to be concerned with (According to the Bible).
Grace and Sanctification (Which are by faith).
Side Note:
We are washed of our sins when we are first saved by God’s grace.
But we must be washed a second time.
Leviticus 13:58
”And the garment, either warp, or woof, or whatsoever thing of skin
it be, which thou shalt wash, if the plague be departed from them, then it shall be washed
the second time, and shall be clean.”
Revelation 7:14
”And I said unto him, Sir, thou knowest. And he said to me, These are they which came out of great tribulation, and have washed their robes, and made them white in the blood of the Lamb.”
