Sorry, but this is not about sanctification and not salvation.
This has every bit to do with salvation. The foundation of our faith is our Lord, if you say He is your Lord then your faith will be built of this and you will hear and do His sayings. Those who partakers in Christ and the Holy Spirit can still fall from the faith. The scriptures say we are molded and worked to perfection.
Hebrews 6:4-6
For it is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, and have tasted the goodness of the word of God and the powers of the age to come, and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
Hebrews 3:12-14
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end.
