I see from scripture that one could forfeit his salvation.
In two ways. One is by just abandoning and walking away from God. Another way is to return to a life of sin and loose our God conscienceness.
JOHN.3: = 18 “He who believes in Him is not condemned; but
he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
1TIMOTHY.4: =
The Great Apostasy
4 Now the Spirit expressly says that in latter times some will
depart from the faith, giving heed to deceiving spirits and doctrines of demons, 2 speaking lies in hypocrisy, having their own conscience seared with a hot iron, 3 forbidding to marry,
and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth. 4 For every creature of God
is good, and nothing is to be refused if it is received with thanksgiving; 5 for it is sanctified by the word of God and prayer.

2THESS.4: = 7 I have fought the good fight, I have finished the race, I have
kept the faith. 8 Finally, there is laid up for me the crown of righteousness, which the Lord, the righteous Judge, will give to me on that Day, and not to me only but also to all who have loved His appearing.

Scripture says salvation is forfeited by ceasing to believe in Jesus Christ or departing from the faith(= apostasy) or losing faith.(opposite of "kept the faith" is "lose the faith")
....... "I have kept the faith" or "I have kept believing" is not the same as "I have kept doing good works or kept the Law or kept obedience", even though faith produces good works and faithlessness produces evil-works.
Trying to define what are good works and evil works can be tricky. Those who have departed from the faith are those who are "forbidding to marry, and commanding to abstain from foods", ie enforcers of certain laws/commandments or good works, obedience or holiness.
