What is the Sign and Seal?

This is the first part of our seven part series on baptism.  The purpose of the series is to give an overview of baptism so people who are curious about infant baptism will be exposed to arguments in favor of infant baptism.  This first video is a summary of a sign and seal.  Is baptism a sign and seal of our faith or the promises of God? 

(I apologize for the music. The music is turned way lower or completely off. I upgraded the mic for the camera so no need for background distraction.)

Here is a link to the “Introduction to Baptism” playlist.
