"Because he hath despised the word of the Lord, and hath broken his commandment, that soul shall utterly be cut off; his iniquity shall be upon him." (Numbers 15:31)

Under the Mosaic law, there was ample provision for forgiveness of sins committed unintentionally. "If any soul sin through ignorance, then he shall bring a she goat of the first year for a sin offering. And the priest shall make an atonement for the soul that sinneth ignorantly, and it shall be forgiven him."
In this Christian dispensation, many would say that this harshness of God's law has been replaced by His love. There is abundant pardon for all, since Jesus died for all our sins. Now, all we need is to confess our sins, and He will forgive us, but, "if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, He that despised Moses' law died without mercy under two or three witnesses: Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God?.

Even assuming this warning applies specifically only to those who have wilfully renounced faith in Christ, the question still remains whether one with true saving faith will wilfully sin against the known will of God, as revealed in His Word. "He that saith, I know him, and keepeth not his commandments, is a liar, and the truth is not in him." Brothers and sisters let us be mindful of our Father's will and be in line with at all times, let us daily come to our Father and seek what his perfect will is for us and our family. That we might be glory to the Father and bring honor to Him who has redeemed us through the blood of the lamb.  For we can not say we love the Lord our God and not keep his commandments for if we do, our words are lies and the truth can not be found in us.  Let not our lips be filled with anything that is not of God. Oh heavenly Father, seal my lips if my words are not in line with your perfect will, cause my hands and feet not bring forth labor if it does bring honor and glory to your name.  For Father I'm bought with price that I can never repay the blood of the Lamb of God, so let my life speak of him, let my words and my deeds come before your throne as a sweet aroma.  Oh father search me and if sin be found in me remove that which does not glorify you.
