I believe you are referring to Colossians 2:14.  For context, let’s read Colossians 2:13-15, “And you, being dead in your sins and the uncircumcision of your flesh, hath he quickened together with him, having forgiven you all trespasses; Blotting out the HANDWRITING OF ORDINANCES that was against us, which was contrary to us, and took it out of the way, NAILING IT TO HIS CROSS; And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.”

What a marvelous look at the power of the Gospel and its results on those who believe on the Lord Jesus Christ.  There was a time that every believer was once dead in their sins. Ephesians 2:1 gives a similar thought by stating, “And you hath he quickened, who were dead in trespasses and sins.”  We were spiritually dead without Christ and, through faith in Him, He ‘quickened’ us, or made us to be alive.  Not only did the Lord quicken us, but He quickened us when He raised Christ from the dead.  He “quickened together with Him” those who are saved.  He did that because ALL our trespasses have been forgiven through faith in the finished work of Christ on the cross.  We have this assurance in 1 John 1:7, “But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son CLEANSETH US FROM ALL SIN.”

What is this BLOTTING OUT THE HANDWRITING OF ORDINANCES that was against us?  Blotting out literally means to “smear out or obliterate.”  That same word is translated ‘wipe away’ in Revelation 21:4, “And God shall WIPE AWAY all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.”  We have a type of that in Numbers, chapter 5.  There, if a man suspected his wife of committing adultery, she was brought before the priest to be tested as to her faithfulness.  If she was found innocent, her accusation was “blotted out” as we read in Numbers 5:23, “And the priest shall write these curses in a book, and he shall BLOT THEM OUT with the bitter water.” 

The HANDWRITING OF ORDINANCES is the written law of ordinances, that is, the Mosaic law. The meaning here is that the burdensome, impossible requirements of the Law are wiped away by the death of Christ.  Although the Law is good when properly used and understood (Romans 7:12, 1 Timothy 1:8), it was against us because no one could keep the Law as the Lord required. The Law could not save.  Indeed, the Law was never meant to save anyone.  It was given to show men their sinfulness and helplessness.  Listen to the words of the Apostle Paul concerning Christ and the Law in Acts 13:38-39, “Be it known unto you therefore, men and brethren, that through this man (Christ) is preached unto you the forgiveness of sins: And by him all that believe are justified from all things, from which ye could not be justified by the law of Moses.” 

So, the Law, while good and holy, could not provide salvation.  Rather, it revealed the sinfulness of man and pointed people to Christ by revealing their need of a savior. With the sacrificial death of the Lord Jesus Christ, the Law was fulfilled for the Lord NAILED IT TO HIS CROSS as a way of publicly showing the debt incurred by sinful man had now been PAID IN FULL by the giving of the Lord Jesus for our sins.  Through the Lord’s death on the cross, His resurrection, and His physical ascension into Heaven, the Lord has publicly displayed the wonderful victory He has won for us.  In this wondrous work, the Lord has accomplished and declared victory over all our enemies.  “Wherefore he saith, When he ascended up on high, he led captivity captive, and gave gifts unto men.” (Ephesians 4:8).
