Those who believe that they can lose their salvation don’t truly have a proper understanding of what salvation is.
The first thing you have to ask yourself is, Did you do anything to GET saved?
No, of course not!
Christ did it all!

So why would you think you would have to do anything to STAY SAVED?

The same one who BEGAN the work in you (Jesus Christ) will PERFORM that work until He comes back (the day of Jesus Christ).

“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:” Phil. 1:6

“…for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.” 2 Tim. 1:12b

The basis of your salvation is the grace of God.
“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God”

You could never save yourself.
God saved you by His grace.
Only God’s grace could save you from your sins.
And it is only God’s grace that KEEPS you saved from your sins.
It is not possible for you to be good enough to keep yourself save because all it takes is one little sin to put you in Hell.
It HAS to be God’s grace that keeps your salvation.
You don’t have the ABILITY to keep your own salvation.

When you were saved, God did a number of things for you that can never be undone.

-- First of all, God GAVE you HIS RIGHTEOUSNESS.

“For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him”
II Cor. 5:21

Jesus Christ was MADE sin so that when you were saved, you were MADE the righteousness of God.

When God the Father looks at you, he sees the RIGHTEOUSNESS of Jesus Christ.
He sees His Son. Perfect and Holy!

You may fail.
But the Righteousness of Christ NEVER fails, and it NEVER leaves you.

-- Next, when you were saved, the Holy Spirit SEALED you until the day of redemption.

“And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption.” Eph. 4:30

When a King set his seal upon something it could never be revoked.

The Holy Spirit has SEALED you until the day of redemption. That can NEVER be revoked by ANYBODY, not even yourself!

-- Next, when you were saved, you were born again.

Can a baby be unbirthed?
No, of course not.

Once you are born again, it is impossible for you to be “unbirthed.”
You may become a wayward child and turn your back on the Father, but you will ALWAYS be His child - just like in the story of the Prodigal Son.

-- Next, when you were saved you were put into the love of God in Christ Jesus.

The Bible says that there is NOTHING that can separate you from that love.

“For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.”Rom. 8:38, 39

Notice how those verses mention “things to come.”
That means that NOTHING in the future that YOU DO or ANYBODY ELSE DOES is able to separate your from God’s love in Christ Jesus.

-- Next, when you were saved, you were actually PLACED IN HEAVEN.

Believe it or not, you are ALREADY in HEAVEN.
You were SEATED in Heaven when you got saved.

“Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved
And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:” Eph 2:5, 6

When you got saved, God SAT YOU DOWN in Heaven!

You don’t have to worry about whether you might lose going to heaven.
Spiritually, you are ALREADY THERE!

-- Next, when you were saved, you were given the Holy Spirit as the earnest of your inheritance.

“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.” Eph. 1:12, 13

In Real Estate, earnest money is money that is given to show that you are “earnest” or serious about buying a house. If you decide not to buy the house, the seller gets to keep the earnest money.

The Holy Spirit is your earnest. You get to keep him no matter what.
That means if you could lose your salvation and go to hell, the Holy Spirit would have to go to hell with you!
Not only that, but Christ also came to reside in you at salvation. He said that He would NEVER leave you nor forsake you, so He would have to go to hell with you too!

There is a lot more I can list, but I hope this gives you a better understanding of what happened to you when you got saved.

Salvation was not just something you received. It was something you BECAME.
You BECAME a child of God.
You BECAME a new creature.
You BECAME a temple of God.
You BECAME a King and a Priest.
YOU BECAME SAVED.

There is no going back on these things!
AMEN!

Now, having said all that, there ARE verses in the Bible that indicate “losing salvation.”
THAT’S when “rightly dividing” comes in to play.
You’ve got to know WHO those verses are written to.

It IS possible for other people in other dispensations to lose the salvation track God gave them.

But after the grace-work of Christ was completed at the cross, a WHOLE NEW SYSTEM was enacted and the born again child of God got into something NOBODY was EVER able to get into before that.
