Hebrews 6:3

1 Therefore let us leave the elementary teachings about Christ and go on to maturity, not laying again the foundation of repentance from dead works, and of faith in God,

2 instruction about baptisms, the laying on of hands, the resurrection of the dead, and eternal judgment.

3 And this we will do, if God permits.

4 It is impossible for those who have once been enlightened, who have tasted the heavenly gift, who have shared in the Holy Spirit,

5 who have tasted the goodness of the word of God and the powers of the coming age—

6 and then have fallen away—to be restored to repentance, because they themselves are crucifying the Son of God all over again and subjecting Him to open shame.

7 For land that drinks in the rain often falling on it and that produces a crop useful to those for whom it is tended receives the blessing of God.
