Yes.
Romans 11:29
"""For the gifts and calling of God are unchangeable - irrevocable .""
So, Salvation is a FREE GIFT....."the gift of righteousness".
Paul explains in Romans 5
15 But the free gift is not like the offense. For if by the one man's offense many died, much more the grace of God and the gift by the grace of the one Man, Jesus Christ, abounded to many.
16 And the gift is not like that which came through the one who sinned. For the judgment which came from one offense resulted in condemnation, but the free gift which came from many offenses resulted in justification.
17 For if by the one man's offense death reigned through the one, much more
those who receive abundance of grace and of the gift of righteousness will reign in life through the One, Jesus Christ.)
18 Therefore, as through one man's offense judgment came to all men, resulting in condemnation,
even so through one Man's righteous act the free gift came to all men, resulting in justification of life.
Romans 5:15-18
The free gift has come to all men.
Will all men be saved?
Paul explains in the next Chapter, Romans 6 -
1 What shall we say then? Shall we continue in sin that grace may abound?
12 Therefore do not let sin reign in your mortal body, that you should obey it in its lusts.
13 And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God.
14 For sin shall not have dominion over you, for you are not under law but under grace.
Do you not know that to whom you present yourselves slaves to obey, you are that one's slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness?
We have been given the gift of righteousness, having it credited to our account, and been given a clean slate and a fresh start with out sins forgiven and a new nature.
If we take this gift and squander it and continue in sin and disobedience, after the Lord so graciously has given us the free gift of righteousness, we can surely expect to reap the wages of sin.
DEATH.
Here are instructions in righteousness that are the direct responsibility of each of us who believe:
...do not let sin reign in your mortal body.
...do not present your members as instruments of unrighteousness to sin.
Do you not know that to whom you present yourselves slaves to obey, you are that one's slaves whom you obey,
whether of sin leading to death, or of obedience leading to righteousness?
Obeying the instructions in righteousness from the Lord's Apostles who wrote the New Testament, leads to righteousness.
God is not mocked... whatever a man sows, that is what he will reap.
Obedience leading to righteousness.
Sin leading to death.
14 But each one is tempted when he is drawn away by his own desires and enticed. 15 Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death. James 1:14-15
