Hebrews 6:4-8

For it is impossible for those who were once illuminated, have tasted also the heavenly gift, and were made partakers of the Holy Ghost, Have moreover tasted the good word of God, and the powers of the world to come, And are fallen away: to be renewed again to penance, crucifying again to themselves the Son of God, and making him a mockery. For the earth that drinketh in the rain which cometh often upon it, and bringeth forth herbs meet for them by whom it is tilled, receiveth blessing from God. But that which bringeth forth thorns and briers, is reprobate, and very near unto a curse, whose end is to be burnt.
