Colossian 2:13-15

Colossian 2:13-15 "and you being dead in your trespasses and the uncircumcision of your flesh, He has made alive together with Him, having forgiven you all trespasses, having wiped out the handwriting of requirements that was against us, which was contrary to us. And He Has taken it out of the way, having nailed it to the cross. Having disarmed principalities and power, He made a public spectacle of them, triumphing over them in it."

The words wiped out here is a Greek word exaleipho which signifies a removal or obliteration, of sin (Acts 3:19)of writing ( Col 2:14), of a name (Rev3:15), or of tears (Rev 21:4). So we see here that Jesus has removed permanently the judgement against us.

The word Handwriting used here is the same as a signed confession of a debit owed, a bond or self confessed indictment.

The word it here is of course the cross. In Paul's other writings along with this he shows that Jesus death on the cross and all the suffering, shed blood, and the resurrection are the only means for our ransom from sin, and reconciliation with God.
Through the cross we are free from the slavery of sin and we are restored to God. The cross is the sole means of reinstatement to a relationship with God. See Eph 2:13, Gal 3:13,14, 2Cor 5:14-17, Rom 5:6-15. John also affirms this in Rev 12:10,11.

Paul uses in verse 15 a description of a Roman Generals homecoming, after a great victory, as a way of showing the events of the cross. It shows that God through the cross divested principlities and powers of their uncontested rule and authority. He made a public spectacle of them shows he did not destroy them but that their authority over the redeemed has been curbed. The final judgement against them awaits.
