The first place we will look is Matthew Chapter 3.

In this one chapter, we will take a look at the four words, that show up in the Greek New Testament attached to Baptism. I will use a tried and true method. The 5Ws and H, that is, who, what, when, where, why, and how.  Now I will modify each a question bit to make it releveant to the verse. I will not answer all of these for each verse as things would get a bit long, but will focus on the important parts. If there is something you feel I neglected, please be sure to leave a comment and I will get back to you. 

Let us begin. 

Matthew 3:1 - βαπτιστης (1/12) 
Who is the Baptizer? John
What is he Baptizing? Well so far nothing is listed
When is he Baptizing? 1st Century AD, and this is before the start of Jesus ministry.
Where is he Baptizing? In wilderness of Judea
Why is he Baptizing?  The Kingdom of heaven is drawing near, and this is part of a prophecy that comes from Isaiah as John is not doing this of his own volition, but because it is part of God's plan. 

How is he Baptizing? Well the word itself points to water. So even though John is in the wilderness, he must be near a body of water. 

I'm only doing one verse today, and I will build up on the verses as go. I would like to close today with one further question for you to think on as we proceed, it is the same question that Jesus asked the Pharisees, "The baptism of John, from where did it come? From heaven or from man?" (Matt 21:25)
