Colossians 1:14

Colossians 1:14 He has delivered us from the domain of darkness and transferred us to the kingdom of his beloved Son, in whom we have redemption, the forgiveness of sins.

A few verses earlier, Paul prays that believers would walk in a manner worthy of the Lord.  He then delivers this verse as the only hope they have in accomplishing this task.   You must never forget that Jesus has made you worthy by redeeming you, forgiving your sins, and placing you squarely in His Kingdom.
