Living in Light of our Baptism

Baptism is a way of saying to the world, I have died to my old way of life; I have died to sin; I have been crucified with Christ, and now I will live my life for his glory.  Thus, for those who profess faith in Christ and have been baptized and continue to live in sin, at best, they do not fully understand the meaning of their baptism or, at worst, they are not actually saved.
