If you return to your old sins after you have been enlightened by God, it is a very serious matter

Jesus Ministries, Joan Boney  ... 

Jesus died for our sins.  
 
But after we are enlightened by the Spirit of God to a sin, if we turn away from the truth from God and return to that sin, there is no more sacrifice for that sin.
 

Hebrews 10:26  For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,

 
So if you were a drunkard and then born again and have been freed from being a drunkard and you are enlightened by God to drunkenness being a sin, if you fall away from the truth concerning this sin and return to being a drunkard, there is no more sacrifice for sins.  
 
Jesus was crucified once for our sins.  To return to those sins after we have been enlightened by God to that sin would be to crucify Jesus afresh.
 

Hebrews 6:4-8   For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, And have tasted the good word of God, and the powers of the world to come, If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put HIM to an open shame.



7 For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God:



8 But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.

 
The apostle Peter says it would have been  better if a person had never been enlightened to the truth of God rather than to turn away from that truth and return to old sins.
 
II Peter 2:20-21  For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.



21 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.
 
Jesus says:
 
Revelation 3:5  He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
After we are born again, to return to our old sins has dire consequences.
