Hebrews 6:4-6

For it is impossible to restore again to repentance

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,

if they then fall away,

since they are crucifying once again the Son of God to their own harm

and holding him up to contempt.

Hebrews 6:9-10

9. Though we speak in this way, yet in your case, beloved, we feel sure of better things—things that belong to salvation.
10. For God is not so unjust as to overlook your work and the love that you showed for his sake in serving the saints, as you still do.
11. And we desire each one of you to show the same earnestness to have the full assurance of hope until the end
