In this talk, Tim begins with some apologetics on baptism with regard
to:

a.   How do you baptize? In what name? Is it Jesus’ name alone? Is it
      in the name of Father, Son and Holy Spirit?
b.   Why baptize babies?
c.   Tim then answers the question: Why is baptism necessary for
      salvation, when the Bible teaches we are “justified by faith apart 
      from the works of law.” In this point Tim will get to the heart of the 
      matter. He will first dispel the notion that “apart from the works of
      law” excludes works in any sense. It does not. But he then moves
      on to explain that the Sacrament of Baptism is a completely
      unmerited gift of grace using the example of a Catholic who receives
      this great gift when he or she can do nothing but lay there and poop!
      Baptizing babies is the perfect example of just how much of and
      great of a gift baptism is.

From there, Tim explains the gift of baptism in detailed theological terms
with regard to two major categories:

a.   In terms of the gifts and graces we receive. And:
b.   In terms of the power and accompanying responsibilities the gift
      brings with it. In the words of Tim’s “favorite theologian of our time,
      Uncle Ben from the movie ‘Spiderman:’” “With great power comes 
      great responsibility.”

Tim then concludes his remarks with a challenge from I Peter 3:15 and
CCC 900, which charges all of us, by virtue of the sacraments of

baptism and confirmation that we have received, with both the “duty
and the obligation” to both know and evangelize our Faith.
