Paul wrote to the church at Colossae describing their change of spiritual citizenship. Because they had confessed their faith in Christ, the Father transferred them from the dominion of darkness into the kingdom of His beloved Son. God is still accepting new kingdom citizens today. His Son has already paid the price for our redemption. Yet, just as a new American citizen must take an oath of allegiance to the US constitution, so the one desiring kingdom citizenship must confess faith in Christ.
