Here's more biblical proof that you could never lose your salvation.
According to the Bible, once you believe on Jesus Christ, you not only receive the forgiveness
of sins your spirit has made alive, but the Bible also says that the Holy Spirit of God
comes to reside within you, operating as a down payment on you until God redeems your
body in its entirety at the resurrection.
Ephesians 1-13 states, 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 the Holy Spirit of promise, which
is the earnest of our inheritance, until the redemption of the purchased possession, until
the praise of his glory.
Notice it doesn't say that he's sealed there until you sin again and then he's gone, until
you backslide and he's no longer there, until you get out of church and stop keeping God's
commandments and you're no longer saved.
No, it says that he's sealed there, awaiting the redemption of the body, referring to the
rapture.
This coincides with Philippians chapter 1 and verse number 6 where it states, Being
confident of this very thing, that he which hath begun a good work in you, will perform
it until the day of Jesus Christ.
