Infant Baptism

I think that the biggest and simplest reason for infant baptism is discovered by simply asking the question, "Is the family normatively part of the institution of the church, or not?  Yes, or no?"

I suspect that most folks (whether they baptize infants or not) really want the answer to this question to be, "Yes!"  No believing parent wants to say that his family lies outside the God-ordained spiritual scope of the work of the church.

There are a lot of proof-texts to support the answer "Yes," but the total argument isn't dependent on proof-texts, but rather on the total witness of Scripture.  Infant baptism is best supported by making it obvious.

Focusing on the details of the bark and leaves of all the trees in the forest of Scripture while looking for proof texts, misses the big picture of the forest as a whole. 

In Scripture the big picture is also doctrinal.
