"For 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, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?"

                            -Hebrews 10:26, 28, 29

Many people tend to use Christ's sacrificial death on the cross as an excuse to continue living a sinful lifestyle. It's as if they think they can keep sinning, and God will keep forgiving - over and over again. But the Word of God puts an end to this idea when it says that if we sin willfully (i.e. on purpose), there is no more sacrifice for sins. That is, Jesus did not endure all the pain and agony of Calvary so that we could continue in sin; instead, He died that we might be free from sin!

"But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life."

                            -Romans 6:22

The author of Hebrews puts it well in 10:28-29 when he says that by sinning willfully one is treading under foot the Son of God and treating the blood that He shed as an unholy thing. How could we claim to love God when we are yet holding on to the very sins that put His Son on the cross? The Lord will not allow His amazing grace to be abused!

"We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself..."

                            -I John 5:18 

Let us be careful to remember the words of the apostle Paul: " Be not deceived; God is not mocked..." (Galatians 6:7)
