“For if we sin willfully after we have received the knowledge of the truth,there remaineth no more sacrifice for sins” {Hebrews 10:26}. However,2 Peter 2:20-22 puts it this way,”For if,after they have escaped the pollutions of the world through the knowledge of the Lord and savior,Jesus Christ,they are again entangled in it,and overcome,the latter end is worse  with them than the beginning. For it had been better for them not to have known the way of righteousness than,after they have known it,to turn from the Holy commandment delivered unto them. But it is happened unto them according to the true proverb,the dog is turned to his own vomit again,and the sow that wad washed,to her wallowing in the mire”.
