Are you just dunked?

What I often ponder is how many Christians are there who are Christians only by instruction, religious education or having somebody manipulate them by dunking them in a baptismal pool or sprinkling water on them?

How many of these people come to church every Sunday, take part in the services on Sunday and yet are not known for being Christians, because away from the church they do not act like a Christian? They are Christians by assumption, by manipulation or instruction, rather than by regeneration.—A.W. Tozer, Experiencing the Presence of God, 120
