Col. 2:14
" 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;"
The NLT says it this way,
"He canceled the record of the charges against us and took it away by nailing it to the cross."
This is the sin debt He paid for us on the Cross. I have a feeling you don't understand all this.
Let me explain it for you in short form.
John told us that Christ died for the sins of the whole world.
1 John 2:2
"And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world."
Christ is the satisfaction to God for the sins of the whole world. In other words, he has paid the sin debt of all men.
When Christ died on the Cross the sins of the whole world were placed on Him.
The sin's of man, past, present and future we paid for by Christ when He died on that Cross.
Here's the condition of salvation, unless we repent from the heart believing He did this for us, we will not reap the benefits of the debt He paid.
