Hebrews 6:4-10
6:4 For it is impossible in the case of those who have once been enlightened, tasted the heavenly gift, become partakers of the Holy Spirit,
6:5 tasted the good word of God and the miracles of the coming age,
6:6 and then have committed apostasy, to renew them again to repentance, since they are crucifying the Son of God for themselves all over again and holding him up to contempt.
6:7 For the ground that has soaked up the rain that frequently falls on it and yields useful vegetation for those who tend it receives a blessing from God.
6:8 But if it produces thorns and thistles, it is useless and about to be cursed; its fate is to be burned.
6:9 But in your case, dear friends, even though we speak like this, we are convinced of better things relating to salvation.
6:10 For God is not unjust so as to forget your work and the love you have demonstrated for his name, in having served and continuing to serve the saints.
