This book could have had some clearer direction, but I liked it. Graves did a good job of showing immersion as the biblical means of baptism, and he was fighting infant baptism in his day.
He argued for a biblical administrator, but did not explain his arguments in depth. They were statements THAT the church is the only biblical administrator, but not always WHY the church is the biblical administrator of baptism. That lowered it for me as I've recently been researching this very topic.
